摘要

This study focused on the photocatalytic decolourization of cobaltous phthalocyaninate dye (PcCo) from ZnO suspension solution under artificial UV-A light. The results showed that the photo-decolourization process of this dye process was obeyed to pseudo-first order kinetics. Moreover, the optimization results explained that the maximum value of decolourization efficiency of this dye was achieved at the conditions: initial dye concentration 25 mg/L and the initial pH of dye aqueous solution is equal to 11.01. Arrhenius plot obtained at temperatures ranged (287.15-303.15) K, which is equal to 28.995 kJ mol-1. The thermodynamic parameters were calculated also and determined that the photoreaction is endothermic and non-spontaneous.
