Abstract: The photocatalytic degradation of acetic acid over cadmium sulphidesemiconductor was
investigated. The effect of various parameters, such as pH,concentration of acetic acid,amount of catalyst, effect
of light intensity were observed. A tentative mechanism has been proposed for the phtocatalyticdegradation of
acetic acid using CdS semiconductor as catalyst.
Keywords: acetic acid, cadmium sulphide,photocatalytic degradation, semiconductor
