Abstract

A pretreatment procedure was performed to improve recovery of selenium from enriched egg and dried pork. Samples were digested with only $HNO_3$ in beaker at $150^{\circ}C$ for 3 hrs, and Se was determined by ICP-MS. Recovery of selenium was 94.2%, and its C.V. value was 2.48%. The analytical results of Se by this method were 0.13 - 2.71 mg/kg for egg and 0.36 - 4.19 mg/kg for dried pork.
