A rapid and simple fluorescence spectrophotometric method for determma tion of cerium in ilmenite is studied. Ferric ion and Cr(VI)are ieduced by hydroxylamine hydrochloride; Tl(1)，Au (III)，Pb (1I)，V(V)，Bi ( III)are reduc- ed by aluminum foil. There is no interference from 32 kinds of metal ions co- mmon in ilmenite. Beer's law is obeyed in the range of 5-800 ppb of cerium. Its C. V. for sample containing 2911 ppm and 78 ppm of Ce are 2.6% and 11.60o repectively(n=7).
