电感耦合等离子体发射光谱法测定地质样品中K2O、Na2O、CaO、MgO、Al2O3、Fe2O3、TiO2
Determination of K2O,Na2O,CaO,MgO,Al2O3,Fe2O3 and TiO2 in geological samples by ICP-AES
摘要
Abstract
In this paper,a method for the determination of K2O,Na2O,CaO,MgO,Al2O3,Fe2O3 and TiO2 in geological samples by inductively coupled plasma atomic emission spectrometry(ICP-AES)is established.The main working parameters of the instrument and the analysis of spectral lines,dissolved acid and other melting conditions are studied.The detection limit of each component of the method,the linear range of the working curve,the accuracy and precision of the results are discussed.The results shows that the precision of the method is between 0.57%and 3.09%,and the accuracy is between 0.04%and 2.72%.It meets the detection requirements of"Chemical Composition Analysis of Rock Mineral Samples in Geological Survey Samples".The method is simple,time-consuming,and can simultaneously determine a variety of elements with high precision and good accuracy.It can meet the requirements of batch quantity analysis of K2O,Na2O,CaO,MgO,Al2O3,Fe2O3,and TiO2 of geological samples in laboratory.关键词
