Abstract

The use of magnetic biochar to overcome aquatic environmental problem has received interesting attention in recent years. Several methods in preparing magnetic biochar have been applied including impregnation-pyrolysis, chemical co-precipitation, and reductive co-precipitation. In case of co-precipitation method, the obtained magnetic biochar is relatively stable and easy to handle, that make it important to study. The purpose of this work is to study the influence of mixing time and mass ratio of precursor on preparation of magnetic biochar using this method. The cassava peel (Manihot utilissima) was used as feedstock for biochar preparation. The magnetic biochar which is characterised using FTIR, XRD, and SEM-EDX analysis was successfully prepared and applied as an adsorbent for MB. The optimum mixing time of precursor was identified at 60 minutes and maximum mass ratio was achieved at 1:1 of biochar:Fe3O4. Importantly, it can be known that MB adsorption successfully improved with the increase of mixing time, up to the optimum adsorption capacity at 60 minutes of precursor mixing time. Furthermore, at the mass ratio of 1:1 magnetic biochar displayed the highest adsorption capacity. The parameter in preparation method developed in this work can be used as an additional information in the magnetic biochar preparation

Abstract

Preparation of leaf mango (Mangefira Indica L)-based adsorbent and its evaluation to reduce methylene blue (MB) concentration have been conducted. Two materials: ads-pristine and ads-CTAB which are referred as native leaf mango adsorbent and CTAB modified leaf mango have been prepared in this study. Cetyltrimethylammonium bromide (CTAB) is cationic surfactant usually used to modify and increase the surface area of the adsorbent for a specific purpose. The materials obtained were characterized by the Fourier Transform Infra-Red (FTIR) and the Scanning Electron Microscope (SEM) with general result, there were detected functional groups indicated the active sites on the adsorbent such as -OH, C-O, C=C. Ads-CTAB was specifically characterized with appearing of C-H aliphatic as the tail of CTAB molecule. SEM images show that both materials have roughness surface and irregular cavities. Additional of CTAB on the surface led the more regularly surface. The optimum pH was in basic region (8), while the optimum adsorbent mass and MB concentration are not clearly found due to the chart still increasing. However, the highest qe was found by 0.01 g of ads-pristine and ads-CTAB with the value 967.25 and 950.75 mg g-1 respectively. As the further evaluation, with the 0.5 adsorbent mass it may be applicated on the MB concentration at around 4000 mg L-1. Kinetics model of this adsorption was followed pseudo second order reactions.
