【摘要】:采用盐酸、硝酸、氢氟酸和高氯酸溶解样品,研究采用电感耦合等离子体发射光谱法测定再生铝材料中的镁、铜、钼、锰、镉、铬、铁。试验结果表明:镁、铜、铁对测定结果无影响;酸度在2%测定误差范围内,待测溶液中盐酸体积分数不宜超过15%;在仪器最佳工作条件下,采用基体匹配方法消除铝对测定结果的影响,方法检出限、测定下限分别为0.01~0.04μg/mL和0.03~0.13μg/mL;方法相对标准偏差为0.49%~3.46%,回收率为98.5%~102.4%。方法灵敏度较好,简便、准确、可靠,可用于再生铝材料中多元素的测定。
[Abstract]:Using hydrochloric acid, nitric acid, hydrofluoric acid and perchloric acid dissolved samples, the determination of magnesium, copper, molybdenum, manganese, cadmium, chromium and iron in regenerated aluminum materials by inductively coupled plasma emission spectrometry (ICP-AES) was studied. The results show that magnesium, copper and iron have no influence on the determination results, the acidity is within the error range of 2%, the volume fraction of hydrochloric acid in the solution to be measured should not exceed 15. Under the optimum working conditions of the instrument, The matrix matching method was used to eliminate the effect of aluminum on the determination results. The detection limit of the method was 0.01 渭 g/mL and 0.03 ~ 0.13 渭 g / mL, respectively, and the relative standard deviation of the method was 0.49 ~ 3.46 and the recovery was 98.55 ~ 102.4 渭 g 路mL ~ (-1). The method is sensitive, simple, accurate and reliable. It can be used for the determination of multiple elements in regenerated aluminum materials.
