Solvent extraction and spectrophotomteric determination of Cu (Ii)‎ with dicyclohexyl-18-crown-6

الملخص EN

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.
