Experimental findings show that Ru(Ⅲ) has very strong catalytic effect on the slow reaction between magneson Ⅰ and KIO 4 in acidic medium of HCl solution and pure magneson Ⅰ exhibits a sensitive second differential polarographic wave at -0.50V VS.SCE in the supporting electrolyte of NaOH.On the grounds thus ensuing,a new catalytic method with oscillopolarographic detection has been proposed for the determination of Ru in the range of 0.01～1.0ng/mL by the fixed-time procedure.The detection limit is 0.003 ng/mL Ru.Ru in synthetic sample and real sample has been analysed by this catalytic method with satisfactory results.
