The ozone generated by the ozone generator was used to oxidize lab made acidic arsenic-containing wastewater to synthesize scorodite at 95℃ for 7 h. The effects of oxidizing rate of Fe(II) and initial pH of the solution on the arsenic removal rate and the scorodite formation were studied. The results showed that increasing the oxidizing rate of Fe(II) and initial pH can enhanced As precipitation. With the ozone oxidation, 89.64% arsenic was removed from the solution at initial pH=2, and the scorodite has large particle size and good crystallization.
