A flow injection method for determination for rhodium (III) has been developed based on its
catalytic effect on the oxidation of Nile Blue by periodate at pH 9.20. The reaction was
monitored spectrophotometrically at 630 nm. The effects of reagent concentration and
manifold variables were studied and optimized. The method is linear in the range of 0.030-
30.0 mug. ml (-1) Rh (III). The effects of interfering ions on the determination of Rh (III) have
been studied. The proposed method has been used for the determination of rhodium (III) ...
