原子吸收分析法已广泛应用于惯常试样分析,测定少量、微量与痕量金属元素。但对于较高含量的测定,应用仍然较少。主要原因是,除了对仪器系统的要求较高外,还由于对实验参数的选择与控制要求严格以及标准溶液的配制比较麻烦。然而,在许多情况下,原子吸收用于高含量的测定具有重要的实际意义。例如,测定复杂基体中的硷金属与硷土金属等。近年来,莫胜钧等研究了一些硷土金属等测定时的化学干扰及矿石中大量钙,镁,铅和锌
Atomic absorption spectrometry has been widely used in routine sample analysis, determination of small, trace and trace metal elements. However, for the higher content of the assay, the application is still less. The main reason is that in addition to the higher requirements of the instrumentation system, the selection and control of the experimental parameters are also demanding and the preparation of standard solutions is cumbersome. However, in many cases, atomic absorption has important practical implications for high-content assays. For example, the determination of complex matrix alkaline metal and alkaline earth metal. In recent years, Mo Shengjun et al studied some alkaline earth metal determination of chemical interference and a large number of ore calcium, magnesium, lead and zinc
