摘　　要：以火焰原子吸收光谱法测定重金属铬含量为宗旨,考察了雾化器流量、乙炔流量、氧化剂流量、燃烧头高度、基本改进剂等因素,结果发现,通过实验条件优化,校正系数从0.998265提高到0.999998,该方法能最大程度改善火焰原子吸收光谱法测定铬元素灵敏度低的问题,具有快速、准确、灵敏度高等优点,为与人类密切相关的食品、药品、化妆品、医疗器械等产品中重金属铬含量测定提供一定的参考。The content of hevay metal chrome was determined by flame atomic absorption spectrometry.The factors,such as the flux of atomization device,acetylene and oxidizers,the height of burning head and basic improver reagents,were studied.The corrections coefficient was improved from 0.998265 to 0.999998 under optimum condition.The question of low sensitivity in determining the content of chrome can be solved in maximum degree,and this method has advantages of celerity,nicety,high sensitivity etc,which can provide reference in determination of chrome in the product of closely related human such as,food,drug,cosmetics and medical instrument etc.
