Abstract

A selective and sensitive method for the solvent extraction
and spectrophotometric determination of cerium(IV) with N-phenyl-
p-chlorocinnamohydroxamic acid (N-p-p-Cl-CHA) has been
described. It forms a red colored complex with cerium and the
complex can be extracted with chloroform at pH 9 to 10. The effect
of the pH, reagent concentration, extraction time, stability of color,
diverse ions and stoichiometry of the complex is discussed.
