研究了两种不同预处理树脂方法对ICP-AES测定土壤中稀土元素的影响。结果表明:使用酒精前处理的强酸一号阳离子交换树脂对稀土元素进行分离与富集是一种准确可靠的预处理方法,并针对15种稀土元素选择出了ICP分析中的有效波长。

In order to detect very low contents of rare earth elements of soil,the effects of two methods for pretreating resin on determining rare earth elements of soil by ICP-AES were systematically studied.The result showed that pretreating strong Acid No.1 cati
