Abstract

A study entitled Electrophotocatalysis and Photocatalysis Methods By Using TiO2 For Decolorization of Remazol Red RB and Decreasing of Cd2+ Ion Concentration Simultaneousy has been done. This study aimed to determine the effect of TiO2 photocatalyst of the decrease of Cd2+ and the effect of electrical potential on decolorization of Remazol Red RB and decrease of Cd2+ concentration simultaneously. TiO2/FTO was used as anode, on the other hand carbon was used as cathode, while the UV-C lamp was used as photon source. Electrophotocatalysis and photocatalysis were performed for 240 minutes. The final results were analyzed using UV-Vis Spectrophotometer for determining the absorbance of the Remazol Red RB remained and using Atomic Absorption Spectrophotometry (AAS) for determining Cd2+ remained. The results showed that the percentage of decolorization of dye solution containing Remazol Red RB and Cd2+ ion electrophotocatalysis and photocatalysis methods were 97.57% and 58.54% respectively, while the percentage of ion Cd2+ decrease by electrophotocatalysis and photocatalysis 84.7% and 76.3% respectively. Photocatalysis TiO2 by the addition of electric potential can minimize recombination of electron and hole pair that can decolorization Remazol Red RB and decrease Cd2+ ions concentration better than photocatalysis TiO2 without using addition of electric potential.

Abstract

Garam merupakan kebutuhan pokok manusia yang sampai saat ini belum ada substitusinya. Negara Indonesia masih harus mengimpor garam khususnya untuk keperluan industri karena rendahnya produksi garam yang dihasilkan oleh petani garam dan tidak ada hamparan lahan luas di kawasan pesisir pantai untuk dijadikan ladang garam berskala besar. Oleh karena itu diperlukan cara untuk mengatasi masalah ini. Tujuan penelitian ini adalah untuk memurnikan garam NaCl hasil petani garam agar sesuai dengan standar SNI dan SII untuk industri dengan biaya produksi yang rendah dengan menentukan volume optimum penambahan (NH4)2CO3 dan pengaruh PAC (Poli Alumunium Klorida) terhadap pemurnian garam. Metode yang dilakukan pada penelitian ini dengan cara menambahkan (NH4)2CO3 sebagai bahan pengikat impurities dengan variasi volume 0,8; 1,6; 2,4; 3,2; 4,0 mL lalu flokulan PAC serta penambahan NaOH yang dapat mengendapkan ion pengotor pada garam yaitu ion Ca2+ dan Mg2+, kemudian dilakukan modifikasi rekristalisasi dengan penguapan yaitu dengan model spray. Pada penelitian ini diperoleh kadar NaCl sesuai dengan standar SII dan SNI yaitu kadar air 2,11%; NaCl dengan kemurnian 98,93%; Ca2+ 0,01%; dan Mg2+ 0,09% pada penambahan (NH4)2CO3 20% sebanyak 3,2 mL dan PAC 10 ppm sebanyak 3 mL terhadap 200 mL larutan garam jenuh.
