Abstract：A simple and rapid method for determination of CaO, MgO, Fe2O3, 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 prepared 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 3.79×10-4~1.07×10-2 μg·mL-1. The recovery rates and relative standard deviations (RSD) of the method are in the range of 87.5%~105.6% and less than 1% respectively. Research results show that the method can meet the requirements of rapid chemical analysis for cement.
