SOLVENT EXTRACTION STUDIES ON Zn(II) AND Cd(II) COMPLEXES OF 1,5-DIMETHYL-2-PHENYL-4[(E)-(2,3,4- TRIHYDROXYPHENYL)]DIAZENYL-1,2-DIHYDROXYL-3H- PYRAZOL-3-ONE.

ABSTRACT The  azo-ligand,   1,5-dimethyl-2-phenyl-4-- 1,2-dihydro-3H-pyrazol-3-one   (H3L)  and  its  Zn(II)  and  Cd(II)  complexes   have   been synthesized  and characterized  based on stoichiometric,  molar conductance,  electronic  and infra-red spectral studies. The results showed that H3L reacted with the metals in 2:1 ratio. H3L coordination was through the hydroxyl, azo and carbonyl groups to form 2+ and 2+  respectively.  Solvent  extraction  studies on Zn(II) and Cd(II) using  1,5- dimethyl-2-phenyl-4--1,2-dihydro-3H-pyrazol-3-one were carried out with  CHCl3. ...
