Abstract A simple kinetic spectrophotometric method was developed for the determination of
ultra trace amounts of Rh (III). The method is based on the catalytic effect of rhodium (III) on
the oxidation of o-Toluidine blue by periodate in micellar media. The reaction was monitored
spectrophotometrically by measuring the decrease in absorbance of o-Toluidine blue at 628
nm with a fixed-time method. The decrease in the absorbance of o-Toluidine blue is
proportional to the concentration of Rh (III) in the concentration range 1.0–400.0 ng/mL, ...
