Based on the reaction of chromind(Ⅵ) with thiamine hydrochloride a simple, sensitive method for the fluorimetric deteamination of chromium is developed. The fluoresent species has an excitation and emission maxima at 405nm and 465nm respectively. The sensitivity of the determination of chromium is 1×10^-6mol/L. The method has been applied to determine chromium in wast water and cast iron satisfactorily.
