氢化物发生——原子荧光光谱法测定化探样品中锡的条件因素影响
|
摘要
目前测定元素锡的方法有很多种,如极谱法、碘量法、原子吸收分光光度法、苯芴酮分光光度法等,但这些方法具有一定的缺陷。本文主要探讨氢化物发生-原子荧光光谱法对化探样品中锡的测定,研究各条件因素对锡测定的影响并对消解方法、消解样品温度、介质及其酸度、硼氢化钾浓度、掩蔽剂的选择等进行了优化。
There are many methods for the determination of tin, such as polarography, iodometry, atomic absorption spectrophotometry, phenylfluorenone spectrophotometry and so on, but these methods have some shortcomings. This paper mainly discusses the determination of tin in Geochemical Samples by Hydride Generation-Atomic Fluorescence spectrometry,studies the influence of various factors on the determination of tin, and optimizes the digestion method, sample temperature,medium and acidity, potassium borohydride concentration and masking agent selection.
