Simultaneous Determination of Al, Ca, Fe, K, Mg, Na, Ti and S in Glass Samples by Inductively Coupled Plasma-Optical Emission Spectrometry

摘要: 通过选择分析谮线、处理样品方法和消除干扰因素等实验,建立了电感耦合等离子体发射光谱法同时测定玻璃中的Al2O3、CaO、Fe2O3、K2O、MgO、Na2O、TiO2和SO3的方法,克服了利用常规化学法测定玻璃中各氧化物步骤繁琐、耗时长、工作量大的不足.方法的回收率为95.0%～103.0%,精密度(RSD,n=10)为0.20%～1.72%.方法具有快速、简便、线性范围宽等优点,分析误差满足常规化学分析法的要求.用于钠钙硅玻璃及其制品的分析,结果令人满意.

Abstract: A method for the determination of Al2O3, CaO, Fe2O3, K2O, MgO, Na2O, TiO2 and SO3 in glass samples by inductively coupled plasma-optical emission spectrometry was developed. The sample pre-treatment, selection of analytical lines and interference elimination were studied. The recovery of the method is 95.0%～103.0% for the elements with precision of 0.20％～1.72%RSD (n=10). The method provides the advantages of wide dynamic linear range, high efficiency and simple operation over the conventional chemical method and has been applied to the determination of these components in sodium calcium silicon glass samples and their products with satisfactory results.
