These lactam derivatives were easily synthesized via aminolysis of 2,2'-methylenebis(4-chlorophenol) dimethylester with corresponding diamine compounds in methanol-dichloromethane solvent systems at one step, respectively. The extraction studies of lactam ionophores were performed toward dichromate anion and alkaline and transition metals such as Li+, Na+, K+, Co2+, Hg2+ and Pb2+. All the structures of the ionophores were confirmed by spectroscopic techniques and elemental analysis.en10.1007/s10847-010-9880-7info:eu-repo/semantics/closedAccessLactamChromate extractionPicrate extractionLiquid-liquid extractionArticle7001.02.2020153159Q3WOS:000290454600018Q2
