氢化法原子吸收光谱测定砷、锑、铋等痕量元素是一种较灵敏的分析方法。但方法需要专门的仪器装置和惰性气体,线性范围窄且干扰多。为克服这些缺点,本文研究出一种双喷雾器原子化器并应用于测定岩石矿物中的微量锑,研究了用自己的装置测定锑的最佳条件、预还原剂的影响和溶液的稳定情况,对共存离子的影响及消除也进行了探讨。从而达到了简化手续、避免浪费和提高仪器利用率的目的。一、仪器装置及工作条件自制的GSD-1型原子吸收分光光度计,带有两
Hydrogenation atomic absorption spectrometry determination of arsenic, antimony, bismuth and other trace elements is a more sensitive analytical method. However, the method requires specialized instrumentation and inert gas, with a narrow linear range and many disturbances. In order to overcome these shortcomings, a double atomizer atomizer was developed and applied to the determination of trace antimony in rock minerals. The optimum conditions for the determination of antimony, the effect of pre-reducing agent and the stability of the solution were studied. The influence and elimination of coexisting ions are also discussed. So as to achieve the simplification procedures to avoid waste and improve the utilization of the instrument. First, the apparatus and working conditions Homemade GSD-1 atomic absorption spectrophotometer with two
