Abstract

Degradation of reactant azo dye namely Naphtol Blue Black (NBB), using an Advance Oxidation Process (AOPs) base on photo-Fenton system was conducted at different H202 concentrations (H202 and Fe2+ concentration ratio 500:1, 100:1, 50:1, 10:1, 1:1 , 25:1 and 5:1) and different contact time (0,10,30.60,90 and 120 minutes). The methodology was adapted and modified from pass researchers. The compilation of the varying H20 2 and Fe2 + dosages and the varying UV contact times for the NBB dye make up the experimental matrix. The result from the experiment has shown that ratio of H2O2 and Fe2+ concentration 5: 1 was the ideal operational parameters with 96.96% degradation of 1 x 10-4 mol/L NBB solution in two hours.
