- 摘要:
- 为探索出更科学、简捷的水产品中汞的测定方法,以硝酸-过氧化氢-高氯酸为消解体系,采用湿法消解——原子荧光光谱法测定水产品中的汞。选择仪器最佳工作条件,回归方程为:IF=1 256.444 9C-3.8605,相关系数r=0.999 27;检出限为:0.001 8 μg·kg-1;线性范围为:0~0.2 ng·mL-1;回收率为:91.4%~102.2%;相对标准偏差为:0.39%~4.84%。该方法检测的样品,消解完全,试剂用量少,操作方便,检出限低,检测结果准确可靠。
- Abstract:
- In order to explore the more scientific,more simple method for the determination of Hg in aquatic products,the aquatic product was digested and treated with wet digestion for Hg determination by AFS,using H2NO3-H2O2-HClO4as digestion system.The measurement conditions were optimized and the regression equation was:IF=1 256.444 9C-3.860 5,the related coefficient was:r=0.999 27;Detection limit was 0.001 8 μg·kg-1;Linear range was 0~0.20 ng·mL-1 Recovery was 91.4%~102.2%;Relative standard deviation was 0.4%~4.8%.The sample could be digested completely with few dosage of reagent,be easy operated,had low detect limit and the results were correct and reliable by using this method.
