火焰原子吸收光谱法测定车用尿素中的金属元素

Discussion Metal Elements in Vehicle unsed Urea by Flame Atomic Absorption Spectrometry

使用火焰原子吸收光谱法对车用尿素中8种金属元素含量进行定性及半定量测试。采用contr AA700原子吸收光谱仪扫描测试标准溶液和样品溶液,通过比较吸光度,从而判断样品中的金属元素含量是否符合要求。该方法操作简便,不用制作标准曲线,节约分析时间和成本,能够及时提供检测结果。

Using flame atomic absorption spectrometry to qualitatively and semi -quantitatively test the content of eight kinds of metal elements in vehicle urea.Use contrAA700 atomic absorption spectrometer scan,standard solution and the sample solution were tested.By comparing the absorbance of the sample, whether the metal element content meeting the requirement is judged.The method is simple,needs not make the standard curve,saving analysis time and cost,providing test results in a timely manner.
