Degradation of Malachite Green in Aqueous Solution by Ca~(2+)/H_2O_2
|
Abstract:
The degradation of malachite green(MG) solution(4 mg/L) was improved by Ca2+/H2O2 at pH 7.0.Its oxidation was carried out at different H2O2 concentrations, temperatures and Ca2+ concentrations.The results showed that the decolorization rate of MG was promoted from 20% to 98% by adding Ca2+.The higher the concentration of H2O2, the higher the degradation rate of MG in early 10 min.When the molar ratio of H2O2 to Ca2+ was more than 5, the decolorization rate could reach 98% in 2 h.The higher the temperature, ...
