Photocatalytic is one of the inexpensive and non-toxic techniques for degradation of organic pollutants into harmless substances such as water and carbon dioxide. In this study, simple electrolysis method was used in preparation of Ag/TiO2 and α-Fe2O3/HY catalysts. The physicochemical properties of the catalysts were studied using XRD, FTIR, FESEM-EDX and surface area analysis. The pH of solution plays an important role in the photocatalytic degradation of organic pollutants which influences the surface-charge properties of the catalysts. Ag/TiO2 and α-Fe2O3/HY were used as catalyst on degradation of 2-chlorophenol (2-CP) and methyl orange (MO), respectively. The effect of pH on degradation of 2-CP and MO were investigated over a pH range from 2 to 9. Higher degradation of 2-CP and MO were obtained at pH 5 (74%) and pH 2 (80%), respectively. This finding might be explained by the amphoteric performance of the catalyst using point zero charge (pHZPC). The pHZPC for Ag/TiO2 and α-Fe2O3/HY was found to be at pH 6.3 and pH 7.2, respectively. Hence, the activities of the catalysts may have been affected by the existence of a strong electrostatic field between the positively charged catalysts surface and negatively charged 2-CP and MO caused a pH value lower than their pHZPC give greater degradation.

Electrolysis Method

Remazol Brilliant Blue is a dye waste mostly generated by the textile industry and can be very dangerous to the environment. Plasma electrolysis is a method that can produce hydroxyl radicals in large quantities in order to degrade the dye compounds. This study aims to test the ability of plasma electrolysis method to degrade Remazol Brilliant Blue wastewater using NaCl as electrolyte, with the addition of Fe2+ ion and air injection. Before the degradation process was carried out, permanganometric test was performed to see the production of hydroxyl radicals with the variations of electrolyte concentration and voltage. The degradation process were investigated more specifically by looking at the effect of Fe2+ ion concentration and the initial concentration of Remazol Brilliant Blue. Remazol Brilliant Blue degradation reached 98.5% in 30 minutes where the initial concentration of Remazol Brilliant Blue is 100 ppm, voltage of 750 V, NaCl concentration 0.03 M,with the addition of 40 ppm Fe2+ ion and air injection. The results show that plasma electrolysis with NaCl as electrolyte using air injection has a good potential in degrading dye wastewater in the environment.
