摘　　要：用硝酸预氧化焦粉、氯化锌化学活化法制备了焦粉基碳吸附材料。静态法考察了焦粉基碳吸附材料对水中铜离子的吸附工艺参数、吸附模型、温度对吸附过程的影响。研究表明:焦粉基碳吸附材料对水中铜离子的吸附工艺参数为:铜离子溶液浓度80mg/L、吸附平衡时间50min、吸附温度为40℃、pH为5.0～6.0;该吸附过程符合Langmuir型吸附模型;温度升高有利于焦粉基碳吸附材料对铜离子的吸附,表明该吸附为吸热过程。Prepared coke-based carbon as adsorption material which was used of nitric acid pre-oxidation, zinc chloride were studied by chemical activation. The static state method was used to investigate the absorption properties of cupric in wastewater by coke-based carbon adsorption material and the factors which affect adsorption, such as pa- rameters, absorption model, reaction temperature. The experiment results showed that Cu^2＋ solution concentration was 80mg · L^-1, the absorption equilibrium time was 50min, adsorption temperature was 40℃ and pH was 5.0 6.0. The absorption course accorded with the Langmuir model. Higher temperature was beneficial to adsorption of cupric by coke-based carbon which indicate that the adsorption was endothermic process.
