| dc.description | An on-line procedure for the oxidation of Cr(III) to Cr(VI) was developed. The extent of oxidation was followed using the 1,5-diphenylcarbazide (DPC) spectrophotometric method accommodated in a flow injection analysis (FIA) system. Cerium(IV) sulphate and potassium peroxydisulphate were tested as oxidising agents. Despite the high oxidation power of the peroxydisulphate ion in acidic solution, the use of Ce(IV) is more convenient under dynamic conditions. The best experimental conditions were obtained at 45°C using a 0.025% m/\/Ce(IV) solution in 0.07 M H2SO4 with the Cr(III) solutions containing up to 3.0 × 10-2 M H 2S04. | |
