| Abstract: | A methodological comparison between inductively coupled plasma-mass spectrometry and atomic fluoresence spectrometry was occured for determination of total arsenic in sea products.The samples were digested by HNO3-H2O2.The internal standard added on line and octupole reaction system were used for ICP-MS,and adding before-reducing agent-hydride generation were for atomic fluorescence spectrum.The calibration curve coefficient results of two methods were greater than 0.9995,and the limits of detection were es... |
