Abstract: The sensitization effect of Triton X-100 for the chemiluminescence system of Luminol -KIO4-Ru(Ⅳ) has been first reported. The detection limit of Ru( Ⅳ) has come down to 3.9×10-4μg/ mL. After Au-Os-Ru mixture is separated by reversed phase paper chromatography with di-p-methyl phenyl sulfoxide as the stationary phase,this method can be used in the microdetermination of rutheni-um(Ⅳ). The results of recovery with 95%-106% are satisfactory.

Key words: Ruthenium, Chemiluminescence, Luminol, Triton X-100
