摘要
A new type of poly-chloromethyl styrene chelating resin (CPS-TA) containing tri-dipyridine aniline side group was synthesized from poly-chloromethyl styrene (CPS) and 4′-(4-aminophenyl)-2,2′:6′,2-tri-pyridine. The results of batch adsorption experiments show CPS-TA chelating resin has excellent adsorption capacity for Cu (II), Ni (II), and Pb (II), and the maximum adsorption capacity is 5.02, 3.38, and 1.27 mmol/g, respectively. The thermodynamic parameters indicate that the CPS-TA chelating resin adsorption for ions is a spontaneous process. CPS-TA chelating resin has good repeated use performance, and the CPS-TA-Cu formed after adsorption has excellent catalytic performance for H2O2 degradation of bisphenol A. The paper simulates the adsorption process through column experiments, indicating CPS-TA chelating resin could be used to adsorb and enrich heavy metal ions in wastewater, which provides a new way to effectively solve the problem of treating wastewater that contains heavy metal ions.
