本文采用微波溶解样品 ,火焰原子吸收分光光度法测定白云石中的铁 ,由试样分解产物钙盐自行消除硅的干扰 ,该方法简便快速 ,相对标准偏差小于 1.0 4% ,测定结果令人满意。
In this paper, microwave was used to dissolve the sample and the flame atomic absorption spectrophotometry was used to determine the iron in the dolomite. The calcium decomposition of the sample was used to eliminate the interference of silicon by itself. The method was simple and rapid, the relative standard deviation was less than 1.04% .
