本文利用正交试验法试验了SAF—OP测定钖的条件,络合物的摩尔吸光系数ε=1.4×10~5升/摩尔·厘米、0～5微克/25毫升符合比耳定律。矿样中的杂质元素经TBP—泡沫塑料分离或用硼氢化钾氢化分离,可以测定矿样中微量的钖,方法的标准偏差3％,变动系数不大于10％。
In this paper, the conditions of SAF-OP determination were studied by orthogonal test. The molar absorptivity of complex was ε = 1.4 × 10-5 liters / mol · cm and 0-5 μg / 25 ml was in accordance with Beer’s law. Trace elements in the ore samples are separated by TBP-foam or hydrogenated with potassium borohydride to measure trace amounts in ore samples. The standard deviation of the method is 3% and the coefficient of variation is not more than 10%.
