本文研究了采用双氧水-浓硝酸试管消化冷原子吸收测定生物村料中总汞的方法。并与通氧燃烧,硫酸高锰酸钾回流消化冷原子吸收法作了比较,证明该法具有设备简单,操作容易、伏速,用样量少,适于大肚样品同时处理。平均回收率101%,均优于通氧燃烧法,硫 In this paper, the method for the determination of total mercury in biological material by H2O2-concentrated nitric acid test tube digestion with cold atomic absorption spectrometry was studied. And compared with the oxygen combustion, potassium permanganate reflux digestion and cold atomic absorption method, the method has the advantages of simple equipment, easy operation, volt speed, little sample amount and suitable for the sample processing of the big belly. The average recovery rate of 101%, better than the oxygen combustion method, sulfur
