应用火焰原子吸收光谱法连续测定啤酒中钾、钠、钙、锌、铜、铁、镁、锰等8种人体必需常量及微量元素,尚未见文献报道。本文以啤酒中的钾、钠互为电离缓冲剂,以5%氯化锶为释放剂,以0.1mol。L~(-1)硝酸为稀释剂,采用空气-乙炔火焰对上述8种元素进行连续分析,方法简便快速,灵敏度高,且准确可信,结果令人满意。 Application of flame atomic absorption spectrometry continuous determination of beer, potassium, sodium, calcium, zinc, copper, iron, magnesium, manganese and other eight kinds of essential and trace elements in the human body has not been reported in the literature. In this paper, beer, potassium and sodium each other ionizing buffer, 5% strontium chloride as a release agent to 0.1mol. L ~ (-1) nitric acid was used as diluent, the above eight elements were continuously analyzed by air-acetylene flame. The method was simple, rapid, sensitive and accurate. The results were satisfactory.
