| Abstract: | This article introduced a sensitive, reliable and accurate approach for the determination of mercury in Mitotane using inductively coupled plasma-mass spectrometry（ICP-MS）. The focus of this work is to optimize sample pretreatment procedure by investigating digestion methods, choice of acid system, and the microwave digestion programs. Under the optimized conditions, the detection limit was 0. 005 mg/kg. The relative standard deviation was 7.7 G for six parallel sample analyses. The spike recovery was in the rang of 82.3%-85.7%. The method has high sensitivity, good stability and high accuracy. |
