摘  要：
在高铁酸钾与孔雀石绿的质量比为10∶1,pH值为7.0的条件下,考察腐殖酸与EDTA对高铁酸钾降解水体中孔雀石绿的影响。结果表明,加入少量的腐殖酸和EDTA溶液,孔雀石绿溶液的吸光度降低,有利于高铁酸钾对孔雀石绿的降解;EDTA的加入量过多时,反而抑制高铁酸钾对孔雀石绿的降解;加入2.0 mL腐殖酸和4.0 mL EDTA溶液降解2 h效果较好。

摘  要：
In the condition of the mass ratio of potassium ferrate to malachite green at 10∶1 and pH 7.0,the effects of humic acid and EDTA on the degradation of malachite green by potassium ferrate was studied.The results showed that the absorbance of malachite green solution decreased when adding a small amount of humic acid and EDTA solution.Thus,humic acid and EDTA were benefit to the degradation of malachite green by potassium ferrate.However,when added excessive EDTA,it inhibited the degradation of malachite green.In summary,effective degradation could be obtained when the amount of humic acid and EDTA was 2.0 mL and 4.0 mL respectively;and degradation time was 2 hours.
