英文摘要	A new approach, combining microwave digestion and sensitive determination of selenium by a normal-phase high performance liquid chromatography after derivatization with 2, 3-diamino-naphthalene was proposed to the measurements of trace selenium concentration in natural waters. Two digestions systems, i.e. HNO3 and H2SO4-H2O2, were evaluated and their working conditions were optimized. Under optimal conditions, this approach provides a detection limit of 7.2 pg (with HNO3) or 10.4 pg (with H2SO4-H2O2), a recovery of 99.1% similar to 103.4%, as well as a linear range of 0 similar to 1.5 ng Se(IV). The approach was applied to determine Se concentration in 4 different types of environmental waters (sample volume: 2 mi,) and the concentration levels of 0.20 similar to 0.90 mug/L were found, with recoveries of 99.1% similar to 103.4% by standard addition.
