摘要
研究了用电感耦合等离子体（ICP）对工作场所中的锰、铜和锌进行同时测定的方法。优化了ICP的工作参数：射频功率发生器频率27．12MHz。入射功率为1．2kW，放射功率小于5W，载气流量1．2L·min^-1。三种元素的检出限在0．105～0．500之间．相对标准偏差（RSD）Cn=6）均小于7％．回收率均在94．5％～103．6％之间。该方法用于工作场所中元素的测定，结果令人满意。
To study the method of determination of Mn, Cu and Zn in the workplace at the same time by ICP. The plasma parameters were optimized as follows; The frequency of the power was less than 5W ; flow rate of cartying was 1.2L/min. The recoveries of the method were 94.5 % - 103.6 %. The method is sensitive, accurate and simple compared with other methods, and the results were satisfactory.
