%X A spectrophotometric method has been developed for the determination of Ce(IV) using Hydrazinecarboxymide2-[(2-hydroxyphenyl) methylene (HC22HPM)1 as an extractive reagent .The reagent forms a light yellow colored complex which has been quantitatively extracted into n-butanol at pH 9.7. The method obeys Beer¡¯s law over a range of 1 to 10 ppm. The molar absorptivity is 4.9312 X 105 L mol-1cm-1and Sandell¡¯s sensitivity is 0.02083 ¦̀g cm-2. The propose method is very sensitive and selective. This method has been successfully applied to synthetic and commercial samples.
