自从Hatch和Ott的第一篇报告发表之后,冷蒸汽原子吸收法(CVAA)已有许多改进。该法作为标准方法用来测定环境试样中痕量汞已被广泛地接受。近年来流动注射技术也开始用于环境试样中汞的测定,Andrade利用聚四氟乙烯薄膜能渗透Hg°的特点,设计了一个新的吸收
Since the first report by Hatch and Ott was published, there have been many improvements to cold vapor atomic absorption (CVAA). This method is widely accepted as a standard method for the determination of trace mercury in environmental samples. In recent years, mobile injection technology has also started to be used for the determination of mercury in environmental samples. Andrade has designed a new absorption by utilizing the characteristic of Hf polytetrafluoroethylene film
