Extraction of Some Typical Heavy Metals with a Multidentate Soft-Ligand 2,6-Bis (5,6-dipropyl-1,2,4-triazine-3-yl)pyridine

摘要

2, 6-bis (5,6-dipropyl-1,2,4-triazine-3-yl) pyridine (BDPTP) was synthesized with 2, 6 - dimethyl pyridine and ethyl butyrate as raw materials. And characterized by IR, 1HNMR and element analysis etc. The extraction performance of this kind of complexes for four kinds of cations, Cu(II), Cd(II), Pb(II), Ni(II) is studied in hydrochloric acid system. The results show that the extraction rate of cadmium chloride with BDPTP in dichloromethane can reach to 97.25%. It is meaningful to cadmium chloride wastewater treatment.
