交联腐殖酸CHA对水体中铅的吸附性能
Adsorption performance of lead ion onto cross-linked humic acid in aqueous solutions
摘要
Abstract
A novel cross-linked humic acid（CHA） was synthesized by mixing epichlorohydrine and polyamine.The structure of the product was characterized by FTIR.The main emphasis was given on the effect of various factors on the Pb2＋ adsorption with CHA in aqueous solution.The results show that the CHA possesses excellent adsorption ability for the Pb2＋.The maximum adsorption capacity can reach up to 219.3 mg/g,which is much higher than that of the insolubilized humic acid prepared by heat treatment.The adsorption performance of CHA is enhanced with the increase of the solution temperature and pH.The adsorption process of CHA fits the Langmuir model.关键词
