改性纤维素对电镀废水中Cu^(2+),Zn^(2+),Ni^(2+)的捕集

Treatment of The Cu^(2+),Zn^(2+),Ni^(2+) in The Heavy-metal Waste Water with Sulfohydryl Cellulose.

制备并研究了改性纤维素对Cu2+、Zn2+、Ni2+3种重金属离子的捕集效果。研究了反应时间、药剂用量、pH值、反应温度对其效果的影响。结果表明,在pH值为中性或碱性,反应温度为25℃时,改性纤维素对重金属离子具有较好的捕集效果。今后可进一步根据物质结构与性能的关系对天然高分子进行改性,并加强应用的研究。

Treatment of the Cu2＋,Zn2＋,Ni2＋ in the eleetroplating waste water use the sulfohydryl cellulose. The waster water＇s heavy metal were be caught. In these research we use different way to researched. Under the different pH value, different temperature, time weight. The results showed that the pH to neutral or alkaline, the reaction temperature is 25℃, it had good results of removal heavy metal ions from wastewater. In the future more atte - ntion shouble be paid to explore more effective process for their uage on environment treatment.
