Extraction of complexes of 1,2-dimethylimidazole, 1-ethyl-2-methylimidazole, 1-propyl-2-methylimidazole and 1-butyl-2-methylimidazole with Co(II), Ni(ii0, Cu(II), Zn(II) and Cd(II) from aqueous solutions (I=0.5 at 298 K) with benzyl alcohol was investigated. For each system, the composition of the extracted species, their partition constans and the pH1/2 were determined.
