以高壓分解法前處理之重金屬分析方法探討

Determination of Heavy Metal by Hight Pressure Bomb Digcstion Method for Pretreatment Abstract

並列摘要


The pretreatment of food by high pressure bomb digestion method for heavy metal analysis was studied. The amount of cadmium, copper and lead were deter mined by Inductively Coupled Plasma Atantic Emission Sepetrophotometry (ICP-AES), while mercury are arsenic were determined by Atomic Absorption Spectro-photometry. The recoveries of lead, copper, cadmium, mercury and arsenic added to Hour and swine liver samples were 87-114%, the detection limit of heavy metals which mentioned above were 101 ppb, 3.39ppb, 5.91 ppb, 30ng and 20ng respectively, This method was most saitable for copper analysis.
