Abstract:

The effects of temperature,pH,and the dosages of H₂O₂,CuSO₄ and FeSO₄ on the degradation rate of methyl orange have been investigated.The results show that CuSO₄ and FeSO₄ have synergetic catalytic effects on the degradation of methyl orange.The optimum conditions for degrading 150 mL of methyl orange simulated wastewater whose concentration is 1.5 g/L are obtained as follows:the degradation rate of methyl orange is the highest,when the temperature is 60 ℃,pH is 3.0,H2O2 is 3.75 mL,CuSO4 is 0.75 g and FeSO4 is 0.04 g.

Key words: catalytic oxidation, methyl orange, copper sulfate, hydrogen peroxide, ferrous sulfate
