摘要
采用复合电极对模拟的含Ni2+废水和含Cu2+废水进行了电吸附试验,讨论了不同pH值、电压、初始浓度对吸附效果的影响和电脱附再生的可行性。试验结果表明:以复合电极为电极材料,采用电吸附的方法可以有效地去除废水中的Ni2+、Cu2+。经过多次电脱附再生后,吸附率和脱附率降低得并不明显,所以对重金属离子进行电脱附再生具有可行性。
The composite electrode is used to treat with the wastewater which contained Ni2＋and Cu2＋ in electroabsorption experiments.And we discuss the influence of different pH value,electric voltage,initial concentration on the effect of adsorption and the feasibility of desorption regeneration.The results indicate that Ni2＋and Cu2＋ in wastewater could be effectively removed by electroabsorption with composite electrodes.After several rounds of desorption regeneration,the decrease of adsorption rate and desorption rate is not obvious,so the desorption regeneration for heavy metal ions is feasible.
