摘　　要：水泥化学分析的传统方法,实验过程冗长。本文研究了以王水+氢氟酸+高氯酸+盐酸溶样及采用水泥标准样品配制工作用标准溶液,建立了水泥样品中CaO,MgO,Fe2O3,Al2O3和TiO2五种组分含量快速测定的等离子体发射光谱法(ICP-AES)。讨论了基体干扰、元素的光谱干扰的影响。研究了方法的检出限和精密度,方法的检出限为3.79×10-4μg.mL-1～1.07×10-2μg.mL-1,回收率为87.5%～105.6%,RSD小于1%。研究结果表明,该方法能满足快速检验的要求。A simple and rapid method for determination of CaO, MgO, Fe203, Al2O3 and TiO2 in cement samples by inductive coupled plasma-atomic emission spectrometry （ICP-AES） was developed. In order to carry out the analysis, the cement samples were dissolved with mixed aqua regia, hydrofluoric acid, perchloric acid, hydrochloric acid, and the standard solution was pre- pared by a series of standard cement samples. The matrix interference and the mutual interference of elements under test were studied by ICP-AES. The detection limits are in the range of 3.79×10-4 -1.07 × 10-2μg·mL-1. The recovery rates and rela- tive standard deviations （RSD） of the method are in the range of 87.5%%-105.6% and less than 1% respectively. Research re- sults show that the method can meet the requirements of rapid chemical analysis for cement.
