Contributions to the analytical chemistry of osmium and ruthenium-IX: the dimercapto derivatives of asymmetric triazine as colour reagents for osmium.
The parameters of the reaction of osmium with 3,5-dimercapto-6-(ethylcarboxy)-1,2,4-triazine have been studied and the optimum conditions for the spectrophotometric determination of osmium over the range 0.5-18.0 ppm determined. The coloured product contains the components in the ratio 1:2 metal:ligand.
