Abstract
A spectrophotometric method has been developed for the determination of Ruthdnium,based on their catalytic effect on potassium periodate oxidation of dibromo nitri chlorophosphonazo in H 2SO 4 medium.The optimum conditions of the reaction,thus,have been deternined.The determination limits was 0.02μg·mL -1 ,and the linear range was 0.02 0.25μg·mL -1 .The method has been applied to determine in ore with satifatery results.
