A　highly　effective　approach　was　developed　for　specific　detection　of　bisphenol　A　(BPA)　in　real　samples,　based　on　a　beta-cyclodextrin　(beta-CD)　modified　ionic　liquid-based　carbon　paste　electrode　(beta-CD/ILCPE).　Voltammetry　and　electrochemical　impedance　spectroscopy　measurements　reveal　significantly　improvements　in　the　conductivity　and　compatibility　of　the　sensor,　when　using　an　ionic　liquid　1-butyl-3-methylimidazolium　tetrafluoroborate　(BMIMBF4)　as　a　super　conductive　binder　in　the　composition　of　carbon　paste.　The　introduction　of　beta-CD　as　a　modifier　as　well　as　a　host　molecule　exhibited　obviously　enhanced　sensitivity　and　selectivity　toward　BPA　over　a　wide　concentration　range　of　1.0　x　10(-7)　to　1.1　x　10(-5)　mol　L-1,　with　a　detection　limit　(S/N　=　3)　of　8.3　x　10(-8)　mol　L-1.　Compared　to　classic　carbon　paste　electrodes,　the　BPA　sensor　not　only　possesses　the　inherent　reusability　and　cost　effectiveness,　but　also　shows　better　sensing　performance　and　stability.　This　can　be　attributed　to　the　combination　of　the　high　ion　conductivity　and　non-covalently　interaction　properties　of　BMIMBF4,　and　the　supramolecular　recognition　and　enrichment　capability　of　beta-CD.　The　mechanism　of　electrode　processes　was　also　presented.　The　proposed　sensor　was　successfully　used　in　the　determination　of　BPA　in　real　samples　with　good　recovery.　(C)　2013　Elsevier　B.V.　All　rights　reserved.
