Abstract

In the presence of strong acidity and salicylic acid, the photoreduction process of Cr (Ⅵ) ion with different concentrations was in accordance with the zero order kinetic model, The kinetic model of photocatalytic reduction of Cr (Ⅵ) on TiO2-WO3 composite catalyst still accords with the zero order reaction of surface catalysis
