摘要
建立了金汞齐化-冷原子吸收法快速测定残渣燃料油中的总汞含量的方法，方法检出限为2μg／kg，回收率为103％-112％；与微波消解-原子荧光法进行比对，两种方法的结果一致。但本方法无需进行前处理，避免了前处理过程中汞的损失，具有环保、简便和快速等优点。
A new method for the determination of total mercu- ry in residual fuel oil by gold amalgamation and cold vapor atomic absorption method was established. The detection limit of the method was 2 μg/kg while the recovery was from 103% to 112%. The test results of both the gold amalgama-tion-cold vapor atomic absorption method and the microwave digestion-atomic fluorescence spectrometry method were near the same.
