采用HCL+HF溶解样品,基体匹配法和背景扣除法消除干扰,ICP-AES法同时测定其主量元素铝、锰。实验结果表明,铝、锰的加标回收率均在97.6%~103%之间,相对标准偏差不大于0.48%。
Interference was eliminated by HCL + HF dissolution, matrix matching method and background subtraction method. ICP-AES method was also used to determine the major elements of aluminum and manganese. The experimental results show that the recoveries of spiked aluminum and manganese are between 97.6% and 103%, and the relative standard deviations are not greater than 0.48%.
