A　simple　and　green　method　for　the　determination　of　trace　bisphenol　A　(BPA)　was　established　by　coupling　supported　ionic　liquid　solid-phase　extraction　to　beta-cyclodextrin　modified　ionic　liquids　carbon　paste　electrode-based　electrochemical　detection　(SILs-SPE-ED).　The　synthesized　imidazolium　ionic　liquids　modified　styrene　type　macroporous　resin　was　used　as　adsorbent　for　SPE　of　BPA.　The　experimental　parameters　that　affected　the　extraction　efficiency　were　investigated　and　optimized.　Dynamic　adsorption　test　showed　that　the　maximum　adsorption　capacity　of　BPA　on　the　SILs-SPE　cartridge　was　10.1　mg　g(-1),　and　the　enrichment　factor　was　40.　The　calibration　curve　showed　a　good　linearity　between　the　anodic　current　and　the　BPA　concentration　in　the　range　of　1.0　x　10(-8)-1.0　x　10(-6)　M.　The　detection　limit　was　4.16　nM　(equal　to　0.95　mu　g　L-1).　The　SILs-SPE-ED　method,　with　the　advantages　including　high　sensitivity　and　good　practicability,　was　applied　to　the　analysis　of　real　water　and　plastic　samples,　and　the　results　agreed　well　with　HPLC　method.
