Sažetak

The effect of 2-methyl pyridine N-oxide, 4-methyl pyridine N-oxide, pyridine N-oxide, 8-aminoquinoline, dibenzyl sulfoxide on the extraction of manganese(II) by 4-benzoyl-3-methyl-1-phe-' nyl-5-pyrazolone (BMPP) in benzene from an aqueous buffered solution was studied. Synergistic enhancement was observed in all systems. Equilibrtum extraction constants and adduct formation constants were calculated. The results showed that synergistic extraction is due to the formation of adducts such as Mn(BMPP)2B where B represents the auxiliary ligand.
