原子荧光光谱进样技术的研究进展

摘要

原子荧光光谱已成为检测金属或类金属的重要手段,其仪器进样方式与所用原子化器类型直接相关.根据进样原理的不同,综述了原子荧光光谱仪器的直接进样、喷雾进样、化学蒸气发生进样和电热蒸发进样4种进样技术,详细介绍了原子荧光光谱各进样技术特别是化学蒸气发生进样和电热蒸发进样的发展历程、原理及优缺点,展望了原子荧光仪器进样技术的发展前景.引用文献75篇.%Atomic fluorescence spectrometry(AFS) has become an important means for detection of metal and metalloid.Sample introduction technique for AFS is directly related to the type of incorporated atomizer.In this paper,according to the difference of sample introduction principles,four kinds of sample introduction techniques of AFS,including direct injection,spray introduction,chemical vapor generation(CVG) and electrothermal vaporization (ETV),were reviewed respectively.The research development,principle,merit and demerit of each kind were presented in detail,particularly that for CVG and ETV.The perspective of sample introduction techniques for AFS in future was also put forword.Totally,75 references were cited.
