摘要：

A　rapid,　effective　and　environmentally　friendly　method　to　determine　parathion　in　water　by　HPLC　with　ionic　liquid-based　solvent　bar　microextraction　(SBME)　was　introduced.　The　influence　of　extraction　parameters　including　extraction　solvent,　pH　of　donor　phase,　extraction　time,　extraction　temperature　and　stirring　speed　was　investigated.　The　parathion　enrichment　factor　was　120　under　optimum　conditions.　The　linear　range　was　1-100　ng/mL　with　a　squared　regression　coefficient　of　0.9982　and　the　detection　limit　was　0.1　ng/mL　(S/N=3).　The　recoveries　of　spiked　samples　range　from　90.1%　to　101.4%　with　a　relative　standard　deviation　lower　than　5.0%.　It　is　needless　to　filtrate　or　separate　for　aqueous　samples　compared　with　other　extraction　methods.　©　2008　IEEE.
