On-line Electrochemical Oxidation of Cr(III) for the Determination of Total Cr by Flow Injection-Solid Phase Spectrophotometry

A novel on-line oxidation method of ultra-trace Cr(III) dissolved in natural water has been developed using a flow electrolysis cell. This method was successfully applied to the determination of the total Cr concentration by flow injection-solid phase spectrophotometry using diphenylcarbazide as a c...
