摘要
水溶液样品用超声雾化法雾化经加热后用常规冷凝器和浓H_2SO_4吸收法去溶,然后引入微波等离子体。详细考察了载气流量、微波功率和HCl浓度等实验条件的影响和KCl对谱线的增强作用。测定了一些地质样品中的铁,得到了满意的结果。
Aqucous sample was introduced into MIP using an ultrasonic nebulizer. In present work the desolvation was ashicved by means of a heated tube, a conventional condenser and a concentrated H_2SO_4 cell. Various experimental parameters such as carrier gas flow rate, microwave forward power and HCl concentration were investigated in detail. It was found that spectroscopic enhance- meat is at tained in the prescnce of KCl. The method has appllied to determine Fe in some grological samples and the results were satisfactory.
