摘　　要：采用反相乳液法制备镉离子印迹聚合物用于去除废水中的镉Cd(Ⅱ)离子,采用BoxBehnken实验设计响应面分析法,以镉离子印迹聚合物的吸附量为响应值,对吸附时间、吸附温度和溶液pH值等参数进行实验设计得到响应面模型。结果表明:对模型进行方差分析得到的F值和R2值分别是15.56和0.952 4,二项式回归方程能够很好地反映和预测本实验所得到的结果;吸附时间、吸附温度和溶液pH对的镉离子印迹聚合物吸附量的影响显著,其影响顺序是由大到小分别为吸附时间,pH,吸附温度。Cadmium ion imprinted polymers were prepared by using inverse emulsion method and used to remove Cd（ II ） from aqueous solution. Response surface method of Box-Behnken de-sign was applied with the adsorption capacity of cadmium ion imprinted polymers as the response value, adsorption time, temperature and pH as parameters. Results suggest that the values of F and R2 obtained from the analysis of variance model are 15. 56 and 0. 952 4, respectively. It is concluded that binomial regression equation can well reflect and predict the results obtained in this experiment; Adsorption time, temperature and pH have significant impact on the adsorption capacity of cadmium ion imprinted polymers, with a decreasing sequence of adsorption time, pH , and temperature.
