Abstract
Two procedures are proposed for determining rhodium using indicator re actions of catalytic oxidation of Methyl Orange or Sulfarsazene with s odium periodate in the continuous-flow mode. The analytical range of r hodium is 1.0 x 10(-3)-1.0 x 10(-2) mu g/mL, for Methyl Orange and 5 x 10(-4)-1.0 x 10(-2) mu g/mL for Sulfarsazene. The throughput of the s ystem is 30 samples per hour. The procedures were used for determining rhodium in State Standard reference samples.
