摘　　要：为获得性能更强的腐植酸基水处理材料,以陕西黄陵风化煤、苯酚、甲醛为原料,制备出酚醛腐植酸离子交换树脂,并分析酚醛腐植酸树脂在不同初始浓度、吸附时间、吸附温度条件下对Cu^(2+)的吸附和解吸性能.结果表明,以25g/L的比例向210mg/L的Cu^(2+)溶液中加入酚醛腐植酸树脂,吸附3h即可达到吸附平衡,最大吸附容量为8.231mg/g,吸附结果符合Freundlich等温吸附模型.实验表明,酚醛腐植酸树脂经洗脱后可重复使用,酚醛腐植酸树脂对Cu^(2+)有良好的吸附和解吸特性.In order to obtain humic acid-based water treatment material with better property,the phenol formaldehyde-humic acid resin was prepared with the raw materials including weathered coal in Shaanxi Huangling,phenol and formaldehyde.The adsorption and desorption properties of the resin for Cu^(2+)under different initial concentration,adsorption time and adsorption temperatures were studied.The result shows that when the rate of the resin and the water is 0.025 g/mL,initial concentration of Cu^(2+)210 mg/L,adsorpting time 3 h,the adsorption capacity can get a maximum of 8.231 mg/g.The experimental data is in accorandance withFreundlich adsorption isotherms model.The desorption experiment shows that the resin can be reused,and has good adsorption and desorption properties for Cu^(2+).
