摘要
以金属铝为阳极 ,采用电化学方法处理腐殖酸模拟废水 ,着重考察了溶液起始 pH值、电压、腐殖酸起始浓度与电解时间等因素对去除效果的影响。结果表明 ,在一定条件下牺牲阳极电解法可以十分有效地去除水体中的腐殖酸。腐殖酸的去除可能是·OH、H2 O2 氧化 ,直接电化学氧化和电凝聚共同作用的结果。
Electrochemical treatment of humic acid in water with Alminum anode was investigated. The influences of factors such as applied voltage, initial value of pH, initial humus acid concentration and electrolysis time on removal rate for humus acid were examined, respectively, and the removal mechanism was also discussed. The experimental results showed that humus acid in water could be removed effectively by electrochemical treatment. The removal of humus acid might result from·OH and H 2O 2 oxidation, direct electrochemical oxidation and electro-coagulation.
