Abstract The extraction of nickel(II) from aqueous hydrochloric acid solution by I-phenyl -3-methyl-4-benzoylpyrazol-5-one (PMBP·OH) dissolved in carbon tetrachloride has been studied. The extraction of nickel(II) from the aqueous solution in the range of 1.0-5.0 M hydrogen ion concentration has been found to be much higher compared to that of cobalt(II). The extraction of nickel with PMBPOH is simple, fast and selective. The composition of the extracted species in solution as well as in solid form have been studied. The IR bands for the reagent and the metal complexes are reported.

Liquid-Liquid Extraction of Cu(II) ion in aqueous solution by dicyclohexyl-18-crown-6 as extractant in dichloroethane was studied .The extraction efficiency was investigated by a spectrophometric method. The reagent form a coloured complex which has been a quantitatively extracted at pH 6.3. The method obeys Beer`s law over range from (2.5-22.5) ppm with the correlation coefficient of 0.9989. The molar absorptivity the stoichiometry of extracted complex is found to be 1:2. the proposed method is very sensitive and selective.
