尽管元素的蒸气发生技术发展到今天己经有一百多年的历史，但这项技术在现代分析科学中仍然扮演着重要的角色，并且仍在不断的创新、发展。伴随着蒸气发生新技术新方法的不断涌现，可蒸气发生元素的范围不断扩大，原子光谱分析的检测灵敏度不断提高，蒸气发生进样已经成为测量复杂基体中痕量特别是超痕量元素的一种常规的进样方法。化学蒸气发生法主要包括氢化物发生、卤化物发生、烷基化物发生、氧化物发生和光诱导/催化蒸气发生等方法。常用的蒸气发生进样方法是采用硼氢化物-酸体系的传统氢化物发生法，此方法进样效率高，但是也有以下缺欠：（1）易受过渡金属离子如Cu2+、Ni2+、Co2+等的干扰；（2）硼氢化物溶液（NaBH4或...Although the sample introduction technique of chemical vapor generation (CVG) has been developed for over 100 years, it sill plays an important role today in modern analytical atomic spectrometry. The technique has become popular for the determination of trace elements in the complex matrices, and new approaches continuously comes forth to improve its efficiency and expand the scope of its applica...学位：理学硕士院系专业：化学化工学院化学系_分析化学学号：2052008115165
