title: Simultaneous determination of Ru(III) and Rh(III) using octadecyldithiocarbamate by first-derivative spectrophotometry.
abstract: A first-derivative spectrophotometric method is described for the simultaneous determination of Ru(III) and Rh(III) using octadecyl dithiocarbamate. The complexes are insoluble in water, but easily extractable into chloroform. Quantitative determination of Ru(III) and Rh(III) is possible in the ranges 0.5-6.0 mug ml(-1) and 1.0-10.0 mug ml(-1) respectively, with a standard deviation of +/-0.10. A statistical evaluation of the experimental results is reported.
