用火焰原子吸收光谱法测定铜、铅、铁、锑、铋现已是最普通的分析方法,目前锡粉中这些元素的测定方法还没有查到,只查到锡锭中这些元素的测定,但是大都采用化学法分析,操作手续繁杂,而且还用有机试剂萃取污染环境。根据原子吸收光谱的优点,联用原子吸收分光光度计的专用微机系统,对分析数据进行处理。对锡粉中以上元素进行了试验,选择最佳溶样方法和测定条件,可在一份样品中连续测定这些元素,直接打印出分析结果,其分析结果与化学法分析结果一致。
Determination of copper, lead, iron, antimony, bismuth by flame atomic absorption spectrometry is now the most common analytical method, the determination of these elements in tin powder has not been found, only to determine the determination of these elements in tin ingot, However, most of the chemical analysis, complicated procedures, but also the use of organic reagent extraction pollution of the environment. According to the advantages of atomic absorption spectrometry, a special microcomputer system of atomic absorption spectrophotometer was used to process the analytical data. The above elements in the tin powder were tested, the best choice of sample solution and determination of the conditions, in a sample of these elements can be measured continuously, print the analysis results directly, the analysis results and chemical analysis of the results.
