The toxicity and chemical properties of selenium depend on the concentration and the chemical structure present in the natural environment. Inorganic selenium is more toxic than organic selenium, thus the accurate determination of inorganic selenium in various samples is needed. HG-AAS(Hydride Generation Atomic Absorption Spectroscopy), HPLC-ICP-MS(High Performance Liquid Chromatography-Inductively Coupled Plasma-Mass Spectrometry) and GC-MS(Gas Chromatograph-Mass Spectrometry) are the current of methods for the determination of inorganic selenium. However, these methods have the disadvantage of expensive equipment, complicated sample preparation and long analysis time. A new analytical method was developed using the SPE membrane filter with LIBS for the determination of inorganic selenium species. The detection limit of inorganic selenium by the new analytical method was 11.21 mg / kg, and the recoveries of Se (Ⅵ) 98.5 ± 5.31% and 101.80 ± 2.01%, respectively. This new speciation method is cost effective, simple and not labor intensive for the quantitation of inorganic selenium.
