电感耦合等离子体发射光谱法是一种简单、准确、快速地测定丁辛醇废催化剂中铑的方法。本文对样品的预处理和检测方法进行研究和对比,通过试验论证该方法的准确性。试样经硫酸-过氧化氢-盐酸溶解,于稀盐酸体系中,用电感耦合等离子体原子发射光谱仪以标准曲线法测定试液中铑的浓度,计算样品丁辛醇废催化剂中铑的质量分数。试验结果表明,该方法简便、有效、准确度较高,适用于丁辛醇废催化剂中铑含量的检测。

Inductively coupled plasma-atomic emission spectrometry is a simple, accurate and rapid method for the determination of rhodium in spent butyl alcohol catalyst. In this paper, the sample pretreatment and detection methods are compared and compared, and the accuracy of the method is proved through experiments. Samples were dissolved in sulfuric acid-hydrogen peroxide-hydrochloric acid, in dilute hydrochloric acid system, using inductively coupled plasma atomic emission spectrometry standard curve method to determine the concentration of rhodium in the test solution, calculate the quality of the sample of butyl alcohol waste catalyst rhodium fraction. The test results show that the method is simple, effective and accurate. It is suitable for the determination of rhodium content in the spent catalyst of butanol.
