摘　　要：使用重金属螯合树脂作为吸附剂用于吸附溶液中的铜离子,在恒温下通过测定不同时刻的吸附量获得吸附动力学及其模型。在恒温下测定不同平衡浓度时的平衡吸附量得到吸附等温线。通过提供实验模型数据处理的相关Excel文件,使用线性拟合和非线性规划求解方法,实现了实验数据的快速化处理。By using a heavy metal ion chelating resin as adsorbent to adsorb copper ions in solution and measuring the amount of adsorption at different times and a fixed temperature,liquid-solid adsorption kinetics and model were obtained.By experimental cooperative arrangements at a same temperature,different equilibrium absorption capacities at different equilibrium concentrations were able to be attained and the relative adsorption isotherm might be determined.By providing relevant Excel files with linear fitting and nonlinear solving methods for experimental data and model processing,the experimental results and models were fast obtained,and the experimental data were fast processed.
