Abstract

Wetland water and acid mine drainage are available in South Kalimantan, Indonesia. However, “Wetland saline water (WSW)” phenomena occur in the wetland areas due to the seawater intrusion, this water which contains a high salt concentration is unsafe to be consumed. While acid mine drainage (AMD) pollution becomes an issue in the mining industry that impact human life and the environment. Salt particles could be removed by using a silica pectin membrane. Banana peel has a high pectin substance. Banana pectin (0.5wt% and 0.1wt%) was employed in silica and calcined at 300 and 400 °C. We demonstrate the silica pectin template’s performance without interlayer for wetland water and acid mine drainage desalination. Membranes were developed through a sol-gel method with silica source deposited from tetraethyl orthosilicate (TEOS) and performed by pervaporation at room temperature (~25 °C). As a result, 0.5wt% banana pectin concentration at 300 °C exhibited excellent performance with the highest water fluxes are 8.4 and 10.4 kg m?2 h?1 for WSW and AMD, respectively. Nevertheless, both membranes achieved high salt rejections up to 92%. Thereby, banana pectin as a carbon source impacts the stronger silica bond.

Abstract

The clean water crisis is increasing along with the increasing human population. Sea water is one of the largest water sources that can be utilized on the earth. However, the high salt concentration dissolved in seawater must be treated before it can use. Desalination is the directly technology for treating seawater with PVDF-TiO2 hollow fibre membrane via pervaporation process. The aim of this research was to determine the performance of PVDF-TiO2 hollow fibre membrane against variations in feed temperature in the artificial seawater pervaporation process. Method for fabrication membrane is using dry-wet spinning method. The result showed that the highest flux permeat occurred at feed temperature of 60ºC, namely 8.96 kg.m-2.h-1 with salt rejection > 92.86%. The result via SEM showed that of the membrane surface morphology, there is a white spot on the membrane surface is TiO2 because the dope solution is too thick. The PVDF-TiO2 hollow fiber membrane in this research is can be applied for seawater pervaporation.

Abstract

Inorganic materials (such as silica and alumina) is a material that is very important and the most desirable in the field of membrane technology. This is due to the physical characteristics and permeation properties owned by the two materials is much better when compared to other polymerbased material. Alumina, for example, this material mostly can be found in clay, and the price is much cheaper as well as easy to find if compared to silica material. The use of peat clay as raw material to produce alumina as membranes support from natural materials would save production costs. This material is also easy to find in South Kalimantan especially around the wetland areas. The aim of this study is to characterize the peat clay as raw material to fabricate membranes module (membranes support). The method is by drying the clay material in uniform particle size (monosize). The raw material powder is then mixed with the organic additives. This organic content provide the hydrophilicity and prorosity agent. Furthermore, it then was calcined and characterized to determine the functional group of the material weather it is more hydrophilicity and porosity. The result shows that the addition of H2O and starch content of functional groups affect the content of the Si-O-Si and Si-O-Al groups on clay material. The content of Si-O-Si and Si-O-Al decreases if content of H2O and starch is higher. It is shown that the streching the Si-OH groups that are more hydrophilic transform into Si-O-Si and Si-O-Al groups that are more hydrophobic. Therefore, the calcined material will be more hydrophobic and more porous.

Abstract

Currently, xerogel has been applied as a filtration material, especially in membrane desalination. However, the xerogel matrix structure for desalination have to be designed properly in order to allow rejection of salt and obtain good hydro-stability, thus, silica precursor in the form of TEOS (tetraethyl orthosilicate)/TEVS (triethoxy vinyl silane) and organic acid catalyst are suitable material for fabrication. The aim of this study is therefore to fabricate and perform deconvolution of TEOS/TEVS xerogel by adding single or dual catalyst, using FTIR (Fourier-transform Infrared Spectroscopy) and Fityk software. The xerogel was fabricated by dried silica sol and calcined using RTP technique (rapid thermal processing) at 450 °C.  Prior to this fabrication, the silica sol was synthesized by sol gel method, using a mixture of silica precursor TEOS/TEVS, ethanol solvent, and varied addition of single catalyst (citric acid) as well as dual catalyst (citric acid + ammonia) for 2 hours, at 50 °C. Subsequently, the xerogel was characterized by FTIR and the deconvolution was obtained through Gaussian approach, with Fityk software. All TEOS/TEVS xerogel samples indicated existence of silanol (Si-OH), siloxane (Si-O-Si) and silica-carbon (Si-C) functional groups. The xerogel deconvolution of TEOS/TEVS using single catalyst exhibit a peak area ratio of Si-OH/Si-O-Si, and this is similar to the dual catalyst counterpart of 0.24 (unit area) and 1.86 (unit area), for Si-C area ratio. This shows the addition of single catalyst was enough to produce deconvolution in TEOS/TEVS xerogel, dominated by siloxane functional group and carbon bonds with the ability to enhance membrane material hydro-stability’s fabrication.

Abstract

Abstrak: Silika thin film dihasilkan dengan menggunakan proses sol gel menjadi bahan keramik anorganik melalui hidrolisis dan reaksi kondensasi. Proses ini bertujuan untuk membentuk sol silika yang memberikan struktur jaringan yang kuat yang dapat diterapkan sebagai film tipis pada fabrikasi membran. Proses ini dilakukan dengan mencampur tetra etil ortosilikat (TEOS) sebagai prekursor utama, etanol dan H2O sebagai pelarut dan asam sitrat sebagai katalis. Konsentrasi asam sitrat yang digunakan yaitu 0,001 % dan 0,005 %. Proses ini dilakukan selama 3 jam  pada suhu 0 °C. Sols dikeringkan dalam oven dan dikalsinasi dalam berbagai suhu (200, 250 dan 400°C) untuk mengetahui rantai karbon dalam  matriks silika. Pengaruh karbon dalam struktur silika kemudian di analisis dengan FTIR dan TGA.Hasil panjang gelombang yang ditunjukan oleh Infra Red diketahui bahwa katalis yang optimum digunakan sebagai yaitu konsentrasi asam sitrat  0,001 %,  karena pada konsentrasi tersebut silanol yang dihasilkan tidak begitu besar jadi dapat menghasilkan ukuran mesopori pada matrik silika dan pH yang dihasilkan adalah 6 sehingga efektif diaplikasikan sebagai pelapis membran. Adapun hasil TGA menunjukkan bahwa suhu kalsinasi optimum yaitu pada 400°C karena terjadi stabilitas termal yang baik, selain itu ikatan karbon juga masih ada pada matriks silika.      Kata kunci: Silika thin film, sol gel, prekursor, kalsinasi, katalis.

Abstract

Corrosion is a chemical phenomenon that often occurs in iron materials that are exposed or immersed in a medium either liquid or air. As a result of this corrosion is fragility and damage to the object so that the object cannot function properly. The purpose of this research is to prevent or slow down the occurrence of corrosion by adding chemicals called corrosion inhibitors which work by forming a protective layer on the surface of objects in the form of metal or iron.In this study, inhibitors were used in the form of NaOH solution with variations in the concentration of 0.1; 0.5; 1; 1.25; 1,5; 5 and 10 N are dissolved in water media and the iron immersion process is carried out at temperatures of 40, 45, and 50 °C. Soaked iron bars are measured for surface area and volume as well as weighing before and after the immersion process so that the corrosion rate is obtained with various variables used. Based on the research results obtained corrosion rate increases with increasing temperature and the addition of NaOH concentration inhibitors. Optimal temperature and concentration to inhibit the rate of iron corrosion is at an immersion temperature of 45 ° C and a concentration of 0.1 N NaOH with a corrosion rate of 0.084875 mpy.

Abstract

Abstrak-Air bersih adalah air sehat yang digunakan untuk memenuhi kebutuhan manusia sehari-hari. Namun pada saat ini ketersediaan air bersih di Kalimantan Selatan menjadi salah satu masalah. Kesulitan mendapatkan air bersih disebabkan kondisi air di kalimantan selatan yang sebagian besar berupa air gambut asin. Air gambut asin merupakan air yang terintrusi oleh air laut saat musim kemarau. Hal ini menyebabkan air gambut ini memiliki tingkat keasinan yang tinggi. Salah satu teknologi yang dapat digunakan untuk mengatasi krisis air bersih ini adalah dengan menggunakan teknologi membran. Membran adalah suatu media berpori, berbentuk film tipis yang berfungsi untuk memisahkan partikel dengan ukuran molekuler dalam suatu larutan. Tujuan penelitian ini adalah untuk menentukan performansi organo silica membrane dengan metode sol gel dengan suhu refluks 50 ⁰C. Penelitian ini menggunakan artificial brackish water (0,3% NaCl) sebagai air umpan. Membran yang digunakan ini dibuat menggunakan metode sol gel  akan di-dipcoating dan dilakukan kalsinasi pada suhu 200 oC dan 600 oC. Nilai flux membran dengan suhu kalsinasi 600 ⁰C sebesar 0,6212 kgm-2h-1 dan nilai salt rejection sebesar 99,37067 % sedangkan pada membran dengan suhu kalsinasi 200 ⁰C nilai flux sebesar 0,5950 kgm-2h-1  dan nilai salt rejection sebesar 99,45831 %. Hasil penelitian ini menunjukan bahwa pada saat  membran dengan suhu kalsinasi 600 ⁰C mempunyai performasi yang lebih baik dibandingkan dengan suhu 200 ⁰C yang disebabkan oleh ukuran pori-pori yang semakin besar terjadi pada membran yang dikalsinasi pada suhu 200 oC. Kata kunci: air gambut, membran, water flux, salt rejection
