Synthesis, characterization and structure effects on extractability and selectivity of N,N′-bis(salicylaldehydene) - 1,4-bIS-(m-ami̇nophenoxy) butane towards some divalent cations.

Microanalytical data, elemental analysis, UV-visible H-1 and C-13 n.m.r. spectra and IR-spectra were used to confirm the structures. The extractability and selectivity of divalent cations were evaluated as a function of relationship between distribution ratio of the metal and pH or ligand concentration. Cu+2 showed the highest extractability and selectivity at pH 6.0, whereas Ni+2 and Co+2 showed at pH 9.2. The stoichiometries of the compounds formed were estimated to be CuL, CoL, NiL, where L is N,N'-bis(salicylaldehydene)-1,4-bis-(m-aminophenoxy)butane. It was concluded that MAS can effectively be used in solvent extraction of copper(II), nickel(II) and cobalt(II) from the aqeous phase to the organic phase.eninfo:eu-repo/semantics/closedAccess[No Keyword]Article975-6287294WOS:0002471502000022-s2.0-342498272301769600710.1002/adic.200790014N/AQ4
