| 摘 要： | 本文运用微波消解，对原子荧光法联测海洋生物中砷和汞的方法进行改进，对仪器条件、微波消解体系、还原剂硼氢化钾浓度等条件进行优化，消除亚硝酸根（NO2）对测定的干扰。本方法经研究改进后，砷和汞的检测限分别为0．02mg／Kg和0．002mg／Kg；相对标准偏差分别为2．83％和2．05％；通过分析验证，改进后的方法简单、灵...

| Abstract: | The method was improved for the simultaneous determination of arsenic and mercury in marine organism with microwave digestion by atomic fluorescence spectrometry.The influence of instrument parameters,digestive system,KBH4 concentration were optimized.The influence of NO-2 was avoided.The developed method showed limits of detection were 0.02mg/Kg for arsenic,0.002 mg/Kg for mercury and relative deviatiaons were 2.83% for arsenic,2.05% for mercury.The improved method,which is simple,sensitive and reliable,ha... |
