电感耦合等离子体原子发射光谱法测定三碘化铑中的铑含量

Determination of Rhodium in Rhodium Iodide by Inductively Coupled Plasma Atomic Emission Spectrometry

试样经盐酸-硝酸混合酸溶解,高氯酸冒烟,于盐酸体系中用电感耦合等离子体原子发射光谱仪在最佳条件下,以标准曲线法测定试液中铑的浓度,计算样品碘化铑中铑的质量分数。实验过程中对样品的预处理和检测方法进行了研究和对比,证明了本方法的准确性。同时本方法简便、有效、准确度较高,适用于碘化铑中铑含量的检测。

In the analytic method of determining the content of rhodium by inductively coupled plasma atomic emission spectrometry （ICP-AES）, hydrochloric acid was used, with hydrochloric acid, nitric acid, perchloric acid trehing rhodium iodide in the electric heating plate.The concentration of rhodium in solution was determined by standard curve method in order to calculate the sample mass fraction of rhodium in rhodium iodide. The methods for sample pretreatment and determination were studied and contrasted. The experiment proved that the accuracy, convenience and rapidness of this method, especially suitable for determining the content of rhodium in rhodium iodide.
