摘要
为了处理废水中重金属污染,本文制备了羧甲基纤维素钠复合树脂(CAA树脂)。结果表明,所制备的吸附剂具有高的强度(压缩应力高到339kPa)。同时,也能对水溶液中Cu^(2+)离子保持高去除效率(80%)。所开发的CAA树脂在去除废水中Cu^(2+)离子方面具有良好的应用前景。
In this paper,sodium carboxym ethyl cellulose composite resin(CAA resin)was prepared to carry out the heavy metal pollution in wastewater.The results show that the prepared adsorbents have good mechanical stability(compression stress up to 339 kPa).At the same time,it can also maintain a high removal efficiency(up to 80%)for Cu^(2+)ions in aqueous solution.The CAA composite resin developed in this paper has a good application prospect in removing Cu^(2+)ions from wastewater.
