目前中国检测工作场所中碱金属和碱土金属元素及其化合物的标准方法是火焰原子吸收光谱法进行检测,该方法操作繁琐,结果稳定性较差。离子色谱法以其快速、方便、选择性好、抗干扰能力强、多组分同时分离与检测等优势,在不同行业中得到了广泛应用[1-3],而在职业卫生领域的应用却很少,国标“GBZ/T160”中仅包含了少数非金属离子的离子色谱检测方法[4]。为进一步验证两种方法在检测碱金属和碱土金属及其化合物中的优劣性,本研究于
At present, the standard method for detecting alkali metal and alkaline earth metal elements and their compounds in China’s workplace is flame atomic absorption spectrometry. The method is cumbersome to operate and results in poor stability. Ion chromatography is widely used in different industries due to its advantages such as fast, convenient, good selectivity, strong anti-interference ability, simultaneous separation and detection of multiple components [1-3], but its application in occupational health Few, GB “GBZ / T160 ” contains only a small number of non-metallic ions ion chromatography detection method [4]. In order to further verify the advantages and disadvantages of the two methods in the detection of alkali metals and alkaline earth metals and their compounds,
