Abstract
Photocatalytic degradation process has been widely implemented in wastewater
remediation and ZnO is extensively researched as the catalyst for the treatment.
Photocatalytic degradation rate of organic pollutants is greatly influenced by impurity
ions. Many studies revealed that certain anions have significant effects on the overall
performance of photocatalysis system. Some of them can either enhance the rate of
photocatalyst reaction or act as inhibitor that causes significant reduction in
photodegradation rate. This study was conducted to investigate the effect of inorganic
anions ( chloride, er, carbonate, col· and sulphate, S042·) on photocatalytic
degradation of methylene blue (MB) dye using ZnO powder.
