Abstract:A comparative study between microwave assisted and sonication methods was carried out to extract arsenic (As) species in shellfish samples using different extractants. Six As species including arsenite [As(III)], arsenate [As(V)], monomethylarsonic acid (MMA), dimethylarsinic acid (DMA), arsenobetaine (AsB) and arsenocholine (AsC) were simultaneously separated and determined by the HPLC–ICP-MS method. The microwave assisted method exhibited higher efficiency than sonication, especially using diluted HNO3 as extractant. By compromising extraction efficiency, pretreatment time and stability of A
