Abstract

|
|
|
Pretreatment method for the determination of total arsenic in seafood sample was studied. NIST SRM 1566a oyster tissue (14.0 ± 1.2 ㎎ As/㎏) as a standard arsenic compound in order to establish the decomposition method. We confirmed that the best way for pretreatment of seafoods to analyze total arsenic content precisely was HNO₃-H₂SO₄-HCIO₄method by comparison of two methods which are dry ashing and wet ashing methods.
