Abstract:
A process for the simultaneous determination of chlorine and chlorate in sodium hypochlorite. First and second streams of sodium hypochlorite are provided. The first stream is treated to generate iodine indicative of chlorine. The second stream is treated to generate iodine indicative of chlorine and chlorate. The iodine of the first stream is subjected to an amperometric measuring cell to generate a first current proportional to a chlorine concentration of the first stream. The iodine of the second stream is subjected to an amperometric measuring cell to generate a second current proportional to the chlorine and chlorate concentration in the second stream. The first current is subtracted from the second current to determine an amount of chlorate.
