For comparison, the corresponding two glyoximes and theirmacrocyclic glyoxime ether derivatives were also examined. Crown ether groups having ligands (L3, L4) carry especially Na+ cation from aqueous phase to organic phase. The extraction equilibrium constants (K-ex) for complexes of ligands with Cu2+ and Hg2+ metal picrates between dichloromethane and water have been determined at 25 degrees C. The values of the extraction constants (log K-ex) were determined to be 12.27, 13.37, 12.94, and 12.39 for Cu2+ and 10.29, 10.62, 11.53, and 11.97 for Hg2+ with L1-L4, respectively.en10.1155/2013/187572info:eu-repo/semantics/openAccessArticleQ2WOS:000320250600001Q4
