摘要
本文首次用Triton X-100敏化Luminol-KIO_4-Ru(Ⅳ)发光体系,配合反相纸色谱法(PTSO为固定相)分离,化学发光法测定了Au-Os-Ru混合液中微量Ru,使Ru(Ⅳ)的检出限降至3.9×10^(-4)μg/mL,比文献值降低了近一个数量级。回收率可达95％～106％。 1 试剂和仪器 Luminol(Merk,95％);Triton X-100(Rohm-Maas,上海化学试剂厂分装);
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.
