摘　　要：ICP—OES法测定水中铟元素，分析过程简单，可以同时分析多个样品、多种元素，在目前的环境监测领域具有很强的适用性[1]。实验采用检出限评定、加标回收率和重复性测试来对分析方法进行确认，实验结果得方法检出限为0．008mggL，加标回收率为94％-103％，测量结果相对标准偏差为2．30％～3．87％，使用标准加入法能够有效消除或补偿样品中的共存元素及基体干扰影响。Indium element analysis by ICP-OES, the process is simple, many samples and elements can be analyzed simulta- neously, in the current environmental monitoring it was applicability. Experimental evaluation using the detection limit, the recovery and repeatability tests to confirm the analytical method, the experimental results obtained detection limit is 0.008mg/L, the recoveries were 94% -103%, relative standard measurement results deviation was 2.30% ~ 3.87%. Use standard addition method can effectively eliminate or compensate for coexisting elements in the sample matrix interference and influence.
