摘要
用空气-乙炔原子吸收光谱法(AAS)对不同溶液中钙元素进行检测,研究了盐酸、硝酸、镧盐对Ca测定的影响。结果表明,在使用原子吸收光谱法测定Ca时,测定结果受到盐酸、硝酸、镧盐严重的负干扰。
The calcium element in different solutions was determined by air-acetylene flame atomic absorption spectrometry,and the influences of hydrochloric acid,nitric acid and lanthanum salt on calcium determination were investigated.The results had the strong negative interference from hydrochloric acid,nitric acid and lanthanum（Ⅲ） during the determination of calcium by flame atomic absorption spectrometry.
