采用高压密闭的方法对赤泥进行样品消解，应用电感耦合等离子体发射光谱仪（ICP-OES）对赤泥中主量、次量与痕量元素进行了测定。通过实验确定了适宜的工作条件，分析了基体效应的干扰因素及消除方法，筛选并确定了各元素的分析谱线，探究了酸度效应、元素之间的干扰等情况。结果表明，本法加标回收率在92.1%~110.2%，检出限在0.000 559~0.083 916 mg/L，可很好地满足实际分析检测要求。

Red mud samples are digested by high-pressure closed method,and the major,minor and trace elements in the red mud are determined by inductively coupled plasma emission spectrometer (ICP-OES).Through experiments,the suitable working conditions are determined,and the interference factors and elimination methods of the matrix effect are analyzed.The analysis spectral lines of each element are screened and determined,and the acidity effects and the interference between elements are explored.It is shown that the recovery rate of this method is between 92.1% and 110.2%,and the detection limit is between 0.000 559 mg·L^-1 and 0.083 916 mg·L^-1,which can well meet the actual analysis and detection requirements.
