... solutions. The initial concentration of the solution being irradiated was also found to have significant effects on the rate of pollutant degradation as well as the kind and concentration of ... effects of initial H2O2 concentration, initial pH of the solution and initial PCB concentration on the degradation of PCBs in water matrix. Journal of Water and Environment Technology, Vol.3, ... H2SO4. The effect of the initial pH of the solution was evaluated using pH values of 3, 7, 5.8 and 10. For the effect of initial PCB concentrations, H2O2 concentrations used were based on the...
