Tingginya konsentrasi fosfor sebagai fosfat ke dalam sistem akuatik mengakibatkan eutrofikasi yang berujung pada terjadinya algae blooming. Input fosfat dalam sistem akuatik ini dicurigai dipengaruhi oleh pelepasan fosfat yang terikat pada besi(III) hidroksida ketika tereduksi menjadi besi(II) di sedimen, sehingga diperlukan pengukuran fosfat dan besi(II) secara simultan. Teknik diffusive gradient in thin film (DGT) merupakan salah satu metode pengukuran in-situ yang dikembangkan untuk pengukuran fosfat dan logam.Teknik DGT diteliti menggunakan binding gel campuran TiO2-Chelex. Metode baru ini memperkenalkan penggunakan TiO2 hasil sintesis melalui metode sol-gel sebagai agen pengikat fosfat dan resin Chelex-100 sebagai agen pengikat logam Fe(II). DGT yang terdiri dari diffusive layer dan binding layer diuji kemampuannya dalam menyerap logam labil besi(II) dan fosfat secara terpisah, kemudian diuji homogenitasnya. DGT dengan binding gel TiO2-Chelex diuji pada sejumlah variasi waktu pengukuran, konsentrasi larutan, dan pH.Hasil analisis menggunakan spektrofotometer AAS untuk logam besi dan spektrofotometer UV-Vis untuk fosfat menunjukkan bahwa waktu optimum untuk pengukuran DGT adalah 24 jam. DGT dengan binding gel TiO2-Chelex optimum mengukur fosfat pada larutan dengan pH 5.2 dan pH 6 dan optimum mengukur besi(II) pada pH netral (pH 7). DGT TiO2-Chelex memiliki kapasitas pengukuran 5.86 mg/L untuk fosfat dan 53.41 mg/L untuk logam besi(II). Sehingga dapat disimpulkan bahwa, binding gel campuran TiO2-Chelex yang telah dibuat dalam sistem DGT dapat menyerap logam Fe(II) dan fosfat secara simultan dengan baik. The high phosphorus as phosphate input into aquatic systems causes eutrophication which leads to the occurrence of algae blooming. Phosphate input in aquatic systems is influenced by the release of suspected phosphate bound to iron(III) when reduced to iron(II) in the sediment. Diffusive gradients in thin films (DGT) technique is one of the in-situ measurement methods developed for the measurement of phosphate and metals. DGT technique was studied using gel bindings mixture of TiO2-Chelex. This new method introduces the use synthesis of TiO2 via sol-gel method and resin Chelex-100 as phosphate and iron(II) binding agents, respectively. DGT composed of diffusive and binding layer was tested for their ability to absorb iron(II) and phosphate separately, and homogeneity. DGT with bindings TiO2-Chelex gel was tested at various measurement time, solution concentration, and pH. The results of the analysis using AAS for iron and UV - Vis spectrophotometer for phosphate showed that the optimum time for DGT measurement is 24 hours. Optimum measurement of DGT with bindings gel TiO2-Chelex was reached at pH around pH 5.2 and 6 for phosphate, and neutral (pH 7) for iron(II). TiO2-Chelex DGT measurement capacity was 5.86mg/L and 53.41 mg/L for phosphate and iron (II), respectively. In conclusion, the TiO2-Chelex mixed binding gel that was made can absorb iron (II) and phosphate simultaneously.

Salah satu cara untuk meningkatkan aktifitas fungsional TiO2dengan menggeser daerah aktifitas atau energi celah pita (Eg) dari sinar ultra violet (UV) ke daerah sinar tampak melalui penambahan zat pensensitif TiO2.Pada penelitian ini, perak klorida (AgCl) digunakan sebagai zat pensensitif TiO2. Tujuan penelitian ini untuk mengetahui pengaruh variasi perbandingan mol awal [Ti8O12(H2O)24]8.Cl8.HCl.7H2O dengan AgNO3 terhadap sifat-sifat fisik TiO2 tersensitifkan AgCl (TiO2@AgCl) yang disintesis dengan metode pengendapan basah dalam suasana asam. Variasi perbandingan awal yang digunakan yaitu perbandingan mol [Ti8O12(H2O)24]8.Cl8.HCl.7H2O :mol AgNO3sebesar 1:9, 1:10, 1:11, 1:12, dan 1:13yang dilarutkan dalam pelarut etanol (total pelarut 37.5 mL). Sampel padat TiO2@AgCl dihasilkan dengan metode pengendapan basah dalam kondisi asam melalui pengontrolan asam HNO3 pada pH~1. Sampel dihasilkan dari penguapan filtrat yang bebas dari endapan AgCl, hingga volume yang didapat setengah dari volume awal. Sampel TiO2@AgCl dikarakterisasi dengan berbagai instrumen: Difraktometer Sinar-X (XRD),Scanning Electron Microscopy-Electron Dispersive X-Ray Analyzer (SEM-EDAX), dan Spektrofotometer UV-Vis Diffuse Reflectance. Hasil penelitian menunjukkan semua sampel TiO2@AgCl berisi 1 fasa nanopartikel (nanokristalit) TiO2 dan 3 fasa kristal yaitu rutil, anatas, dan AgCl.TiO2@AgCl memiliki bentuk morfologi berupa mikrosferik dengan ukuran berkisar 0.5-1 μm. Berdasarkan hasil analisisdengan spektrofotometer UV-Vis Diffuse Reflectance menunjukkan semua sampel TiO2@AgCl mengabsorbsi sinar ultra violet (UV) dengan Eg sebesar 2.87-3.89 eV, dan sinar tampak dengan Eg sebesar 1.60-2.40 eV. Titanium dioxide (TiO2) is a semiconductor that can be applied in the field of photocatalyst, solar cell, anti-bacterial, anti-pollutants, and anti-fogging. The functional activity of TiO2 can be increased by shifting the activity area from ultraviolet (UV) to visible through the addition of sensitizer. In this research, silver chloride (AgCl) was used as a sensitizer The objective of the research is to study the effect of the initial mole comparison of [Ti8O12(H2O)24]8.Cl8.HCl.7H2O and AgNO3on the physical properties of AgCl-sensitized TiO2(TiO2@AgCl). All TiO2@AgCl were synthesized using the wet chemical precipitation method under acidic conditions by the addition of a concentrated HNO3 with pH ~ 1. The initial comparison variation used was the mole ratio of [Ti8O12(H2O)24]8.Cl8.HCl.7H2O : AgNO3 of 1: 9, 1:10, 1:11, 1:12, and 1:13. Each of these materials was dissolved in ethanol to 37.5 ml. All samples were produced from evaporation of filtrate free from AgCl precipitate, until the volume obtained half of the initial volume. The solid samples were characterized using X-Ray Diffractometer (XRD), Scanning Electron Microscopy-Electron Dispersive X-Ray Analyzer (SEM-EDAX), and UV-Vis spectrophotometer Diffuse Reflectance.The results showed that all samples of TiO2@AgCl consisted of 1 phase of TiO2-nanoparticles and 3 phases of rutile, anatase and AgCl crystals. The morphology of TiO2@AgCl is microspheric with a size ranging from 0.5-1 μm. Based on the results of the analysis with the UV-Vis spectrophotometer Diffuse Reflectance showed that all samples of TiO2@AgCl absorb ultraviolet (UV) rays with bandgap (Eg) ranging from 2.87 to 3.89 eV, and the visible light with Eg ranges from 1.60 to 2.40 eV.
