K.Gyobiro提出,“在高铼酸根离子存在下,产生碲酸的极谱催化还原波,适于低浓度铼的测定”。他拟定了含钼矿石中微量铼的分析方法(灵敏度:0.08微克/毫升)。陈永乐改变了底液和测定条件,将灵敏度提高一倍(0.04微克/毫升),用于铜矿、辉钼矿中微量铼的测定。韩雅芳用该催化波测定了痕迹量碲。他们对这个催化波反应机理提出了不同的见解。我们注意到,在含高铼酸根离子的硫酸溶液中,无论加入碲酸根离子或亚碲酸根离子,都产生同样的极谱催化波。还发
K. Gyobiro proposed that “the polarographic catalytic reduction of telluric acid in the presence of perrhenate ions is suitable for the determination of low concentrations of rhenium.” He developed a method for the analysis of traces of rhenium in molybdenum-containing ores (sensitivity: 0.08 μg / ml). Chen Yongle changed the bottom solution and determination conditions, doubling the sensitivity (0.04 μg / ml) for the determination of trace rhenium in copper and molybdenite. Han Ya-Fang with the catalytic wave measured the amount of trace tellurium. They put forward different opinions on this catalytic wave reaction mechanism. We note that the same polarographic catalysis wave occurs in the sulfuric acid solution containing the rhenium ion regardless of the addition of tellurite or tellurite ions. Also sent
