Abstract

Bismuth-based iodine oxide/activated carbon powder catalyst was prepared by means of ultrasonic method through using activated carbon as carrier. At the same time, its photo-catalytic activity was evaluated using methyl orange as the degradation object, xenon lamp as light source. The results showed that the optimum degradation rate was 98.20% when methyl orange initial concentration was 25 mg/L, initial pH=4, catalyst dosage was 0.1 g/100 mL and 1 mL 30% hydrogen peroxide was added. In addtion, hydrogen peroxide could promote the degradation of methyl orange by bismuth-based iodine oxide /activated carbon catalyst.

Key words： photo-catalytic bismuth-based iodine oxide activated carbon methyl orange
