| 中文摘要: |
| 建立了硝酸-硫酸-高氯酸分解样品、钇内标电感耦合等离子体发射光谱法(ICP-AES)测定铑派克废料中的铑含量的方法。对样品处理方法、湿法消解条件、测定精密度和再现性、方法准确度进行了研究。称取铑派克废料约0.6 g，用9 mL硝酸、0.5 mL硫酸和1 mL高氯酸，在200℃加热消解除去有机物，盐酸溶解残渣，ICP-AES测定样品中100~1500 g/t的铑，相对标准偏差(RSD，n=9)为0.41%~1.35%，加标回收率99.1%~99.7%，满足生产测定的要求。 |

| A determination method for rhodium content in rhdium parker waste by nitric acid-sulfuric acid-perchloric acid digestion and yttrium internal standard ICP-AES was established. The sample pretreatment method, wet digestion conditions, assay precision and reproducibility and its accuracy were investigated. Weighed about 0.6 g of rhodium parker waste, and the sample was digested to remove organic matter using 9 mL of nitric acid, 0.5 mL suifuric acid and 1 mL of perchloric acid at 200℃, and the residue was dissolved with hydrochloric acid. 100~1500 g/t Rh in the resulted solution was determined by ICP-AES. The relative standard deviation (RSD, n=9) was 0.41%~1.35%, and the recovery rates of standard addition were 99.1%~99.7%, which met the requirements of production determination. |
