A colorimetric method was developed for the determination of milligram amounts of cerium(IV) on the basis of a color reaction with 2- thenoyltrifluoroacetone in benzene. The bright orange-red cerium(IV)-TTA chelate solution (in benzene) follows Beer's law at 450 m mu over the range of 3 to 40 gamma of cerium(IV) per ml. At pH 4.0 to 6.0, 80% or more of cerium(IV) is removed from an aqueous solution of TTA-benzene in a single extraction. The colored system is stable for 2.5 hours. The determination can tolerate equal amounts of silver, manganese, copper, and cobalt, whereas nickel, bismuth, aluminum, thorium, uranium(VI), citrate, tartrate, and EDTA seriously interfere. The method is accurate and reproducible to within plus or minus 2% and offers a procedure for simultaneous extraction and determination of cerium(IV). (auth)
