- In the present study, canned crab and canned tuna were taken as the quality control samples, and microwave digestion combined with wet-digestion was estimated as the optimum digestion method for animal origin seafood after comparing with the microwave digestion. The quality control samples were digested under microwave first, and then 1 mL HClO4 and 2 mL H2SO4 were added to the digestion solution for wet digestion. Atomic Fluorescence Spectrometry (AFS) was adopted to determine the concentration of total arsenic in quality control samples. The result obtained is close to the assigned value with high accuracy. The relative error ranges from 1.8% to 2.1%. The present study elaborates the experimental phenomena and conversion mechanism of different existing forms of arsenic in details during wet-digestion under HNO3-HClO4-H2SO4 system. And it is effective and convenient to control the time node by analyzing the experimental phenomena which is conductive to ensure the accurate results.
