摘要：

A simple spectrofluorimetric method for the determination of Cr(Vl), based on the oxidation of 8-hydroxyquinoline-5-sulphonic acid with potassium dichromate in 6.3 mol dm-3 H2SO4, is described. The fluorescent species has excitation and emission maxima at 360 and 450 nm, respectively. The fluorescence intensity of the system is linear over the concentration range 5.6 x 10(-6)-1.5 x 10(-5) mol dm-3 Cr(Vl). The method was applied to the determination of Cr(Vl) in industrial wastewater samples.
