Using ferrous sulfate（by-product of tianium white） as iron source and catalyst of photogenic Fenton,the oxidative decomposition of methyl orange by ferrous sulfate-H2O2 system under ultraviolet light was studied.The effect of temperature, concentration of H2O2,wavelength of ultraviolet light,concentration of ferrous sulfate and concentration of Fe2+ on the decolorization rate of methyl orange was investigated.It is demonstrated that the decolorization rate of methyl orange is the fastest which reaches 100% under the conditions of 35 ℃,6.4 mmol/L of hydrogen peroxide,1.0 mmol/L of ferrous sulfate（about 1.0 mmol/L of Fe2+) and 395 nm of ultraviolet light.The decolorization effect of the ferrous sulfate on methyl orange was better than that of pure heptahydrate ferrous sulfate.The work has expanded a new strategy for the effective utilization of the by-product of tianium white,which can be used to treat methyl orange by catalytic degradation
