硅酸岩和化探样品中溴的含量甚微,一般在10ppm以下,这就要求有一个灵敏度较高的分析方法。一般的比色法和离子选择性电极法灵敏度太低,而灵敏度较高的中子活化法则又缺乏特殊装备不能应用。国外对利用动力学分析法测定溴的研究早有报导,1959年Shiota等用催化法在天然水中测定了微量溴。 The content of bromine in silicate and geochemical samples is very low, generally below 10ppm, which requires a more sensitive analytical method. General colorimetric and ion-selective electrode sensitivity is too low, and high sensitivity neutron activation law and the lack of special equipment can not be applied. Foreign studies on the determination of bromine using kinetic analysis have long been reported. In 1959, Shiota et al. Used a catalytic method to measure trace amounts of bromine in natural water.
