POLAROGRAPHIC DETERMINATION OF RUTHENIUM
A method for the polarographic determination of ruthenium is discussed using basic sodium gluconate as the supporting electrolyte. The half-wave potential is --0.67v veisus the saturtred calomel electrode for 0.1 F sodium gluconate at pH 14. For these conditions the diffusion current constant, I, is 1.18 (maximum rather than average current). This constant is applicable for ruthenium concentrations from 1 x 10/sup -4/ to 5 x 10/sup -3/ F; analyses in this concentration range have an average deviation of 2.1%. This procedure and precautions for sample preparation are discussed. Platinum causes serious interference, but low concentrations of palladium and osmium can be tolerated. Iridium and rhodium do not interfere. (auth)
