ICP-AES法测定载金树脂物料中铝、镁、锰、锶的含量

Determination of the content of aluminum,magnesium,manganese and strontium in gold-loaded resin materials by ICP-AES

建立载金树脂物料中的铝、镁、锰、锶4种元素的分析检测方法。采用盐酸-硝酸-氢氟酸加热体系对试样进行溶解,并通过电感耦合等离子体原子发射光谱法同时测定铝、锰、镁、锶元素的含量。实验结果表明,20 g/t的载金树脂物料中铝、锰、镁、锶元素的质量分数分别为4 014、1 802、193.5、109.5μg/g,精密度实验的相对标准偏差为1.07%～3.29%,加标回收率为95.00%～104.40%。该方法快速、准确、稳定,适用于载金树脂物料中铝、锰、镁、锶元素的测定。

An analytical method for determination of the content of aluminum,magnesium,manganese and atrontium in gold-loaded resin materials is established in this study. The samples are firstly disolved in hydrochloric acid-nitric acid-hydrofluoric acid system under heating. Then,inductively coupled plasma atomic emission spectroscopy（ ICP-AES）is used to determine the content of aluminum,magnesium,manganese and atrontium. The results show that the mass fraction of aluminum,magnesium,manganese and atrontium in 20 g/t of gold-loaded resin materials are 4 014,1 802,193. 5 and 109. 5 μg/g,respectively. The relative standard deviation of precision experiment is 1. 07%- 3. 29% and the recoveries is 95. 00%- 104. 40%. This method is rapid,accurate,stable and suitable for the determination of aluminum,manganese,magnesium and strontium in gold-loaded resin material.
