Degradation of Azo Dye Wastewater in a TiO2 Photocatalysis and Membrane Separation Hybrid System

Abstract

Abstract: Nano-titania was prepared by an improved acid-sol method at low temperature (<100 oC). The granularity of TiO2 in aqueous solution was significantly influenced by initial pH according to the zeta potential theory. This induced the variation of photocatalytic activity and TiO2 rejection in the photocatalytic membrane reactor and therefore provided a basis for pore size selection of membrane.

Key words: photocatalysis, titania, microfiltration membrane, azo dye wastewater
