引言在氢化物发生技术与原子光谱分析方法的结合中,基体元素的干扰效应可分为二类:(1)在还原过程中氢化物生成效率的改变引起的干扰;(2)已被还原为氢化物的元素在原子化过程中形成稳定化合物而引起的干扰。可统称为化学干扰。在氢化物发生原子吸收光谱分析中,这二类干扰都是比较显著的。当使用感耦等离子体作激发光源时,由于等离子体的温度很高,而且送入等离子
INTRODUCTION In the combination of hydride generation techniques and atomic spectroscopy methods, the interference effects of matrix elements can be divided into two categories: (1) disturbances caused by changes in hydride generation efficiency during the reduction process; (2) has been reduced to The hydride elements interfere with the formation of stable compounds during atomization. Can be collectively referred to as chemical interference. In the atomic absorption spectrometry hydride generation, these two types of interference are more significant. When inductively coupled plasma is used as the excitation light source, the temperature of the plasma is high, and the plasma
