摘　　要：以活性炭为载体,硝酸铜为活性前驱体,采用浸渍法制备活性炭负载铜催化剂,考察浸渍条件对活性炭碘吸附值的影响。利用单因素方法确定Cu(NO3)2的用量,用Design-Expert7.0软件设计实验方案,建立响应面分析模型。分析认为载铜活性炭的最优制备条件为:硝酸铜溶液质量分数为20%,浸渍时间为64 min,浸渍比(硝酸铜溶液与活性炭质量比)为5.0,最优条件下制备的载铜活性炭的碘吸附值为655.95 mgg。The cupric nitrate supported on activated carbon is prepared by impregnation technology so as to check the effect of impregnation conditions. Based on single experiment method for determining the optimal use level of cupric nitrate, Design - Expert 7.0 software are used to design testing program and establish response surface model. The optimal preparation conditions are, Cu （ NO_3 ） _2 concentration 20%, impregnation time 64 min, impregnation ratio 5.0. Under optimized conditions, the iodine sorption values of activated carbon is 655.95 mg/g.
