Abstract

A simple and sensitive spectrophotometric method for the determination of cerium(IV) was developed. With o-phenylenediamine cerium(IV) gives an orange-red colour with an absorption maximum at 470 nm. The system obeys Beer's law in the range 7 ppm to 500 ppm with a molar absorptivity of 2.4 x 10(3) l mol(-1) cm(-1) and Sandell sensitivity of 0.5 ppm. Interference by various ions was studied. This method was used for the determination of cerium in low-alloy steels and the results are in good agreement with the certified values
