【摘要】 应用电感耦合等离子体原子发射光谱(ICP-AES)法,对硅铝钡合金中的主次量元素Si,Al,Ba,Fe．Ca,Mn,Cu进行同时测定。通过对溶样方法的改进和对ICP-AES光谱仪的分析参数的优化,以及对影响分析结果准确度的因素进行校正,使方法的准确度得到提高。应用本法测定国家标准参考物质的结果与标准值一致,方法准确快速,简便可行,加标回收率为98％～105％,RSD均小于4％。更多还原

【Abstract】 A method of determining primary and lesser elements (Si, Al, Ba, Fe, Ca, Mn, Cu)in barium aluminum silicon alloy by inductively coupled plasma actomic emission spectrometry is reported. The accuracy of this method is increased by improving the way of dissolving samples, optimizing analyzing parameters and calibrating the factors of affecting accuracy . The results by this way are consistent with certified values. This method is accutate, rapid and simple. Its recoveries are in the range of 98%-105%. The relation standard deviation is less than 4%.更多还原
