改性牡蛎壳对废水中Cu²⁺的吸附性能研究
Adsorption Study of Modified Oyster Shell on the Cu²⁺ in Wastewater

以牡蛎壳为原料制备一种新型牡蛎壳负载SDS (十二烷基硫酸钠)水处理剂，研究了水处理剂对水中Cu²⁺的吸附性能。通过单因素实验考察了水处理剂的SDS/牡蛎壳质量比、pH值、吸附时间及温度对吸附Cu²⁺的影响，确定最佳去除Cu²⁺条件。试验分析得出水处理剂去除Cu²⁺最佳工艺条件：SDS/牡蛎壳质量比15%、pH = 8、吸附时间120 min和温度35℃。该研究对以牡蛎壳为基的水处理剂的开发与利用提供科学依据。
The new water treatment agent of SDS (Sodium dodecyl sulfate)-coated oyster shell was prepared by using oyster shell as raw materials. Adsorption performance of water treatment agent on Cu²⁺ was studied and the influences of mass ratio of SDS and oyster, pH value, adsorption time and temperature were discussed by single factor experiments, and the best extraction conditions were ultimately determined. Through the test analysis, optimum extraction conditions of water treat-ment agent on the removal of Cu²⁺ were as follows: mass ratio of SDS and oyster was 15%, pH was 8, adsorption time was 120 min and temperature was 35？C. It would provide scientific basis for the further research and development of water treatment agent based on oyster shell.
