Studies on Hydroxamic Acids : Solvent Extraction of Metal Ions with N-p-chlorophenyl-2-thenohydroxamic Acid

Department of Chemistry, R. S. University, Raipur-492002 Manuscript received 7 February 1977, accepted 27 April 1977 The solvent extraction of several metal ions with N-p-chlorophenyl-2-thenohydroxamic acid is investigated qualitatively. The coloured chloroform extractable complexes of Ce(IV), Cu(II), Fe(II, III), Ti(IV), U(VI), V(V) and Zr(IV) are attractively suited for further examination for colorimetric determination and solvent separation
