酚醛-腐植酸树脂对Cd^(2+)的吸附性能研究

Study on Adsorption Capability of Phenol Formaldehyde-humic Acid Resin for Cd^(2+)

以泥炭和水溶性酚醛树脂为原料,制备酚醛-腐植酸树脂吸附剂,研究了酚醛-腐植酸树脂吸附剂对Cd2+的吸附和解吸性能,讨论了溶液pH、吸附时间对吸附性能的影响。结果表明:酚醛-腐植酸树脂对Cd2+具有良好的吸附和解吸特性,吸附实验数据大致符合Freundlich吸附等温模型。

The phenol formaldehyde-humic acid resin was prepared using peat and hydrotropic phenol formaldehyde resin. Adsorption and desorption capacity of phenol formaldehyde-humic acid resin were studied for Cd^2＋. The effects of adsorption time and pH on the adsorption capability were studied. The results show that the phenol formaldehyde-humic acid resin have good adsorption and desorption properties for Cd^2＋ The experimental data was in accordance with Freundlich adsorption isotherms model.
