一、前言氢化物发生-高频电感耦合等离子体(HY-ICP)发射光谱分析是在氢化物发生-原子吸收光谱分析(HY-AAS)的基础上发展起来的。它是使待测元素生成挥发的共价氢化物,然后将生成的氢化物引入ICP,测量其发射光谱。目前已有十种元素可以利用氢化物发生的方法进行测定,它们是砷、锑、硒、碲、铋、锗、锡、铅、铟和铊。这些元素在实际样品中的含量一般并不高,但起的作用却很大。例如上述一些痕量元素能影响钢的冶金性质。由于其中一些元素具有毒性或致癌作用,必须严格控制它们在 I. Introduction Hydride Generation - High-frequency Inductively Coupled Plasma (HY-ICP) emission spectroscopy was developed on the basis of hydride generation-atomic absorption spectroscopy (HY-AAS). It is to make the element under test generate volatile covalent hydride, and then introduce the generated hydride into ICP and measure its emission spectrum. There are already ten elements that can be measured by the hydride generation method. They are arsenic, antimony, selenium, tellurium, bismuth, germanium, tin, lead, indium and thallium. The content of these elements in the actual sample is generally not high, but plays a very large role. For example, some of the above trace elements can affect the metallurgical properties of steel. Because some of these elements are toxic or carcinogenic, they must be strictly controlled
