Bisphenol　A　(BPA)　is　widely　employed　in　the　production　of　plastic　bottles　and　food　packaging.　However,　excessive　BPA　poses　significant　environmental　and　biological　risks,　highlighting　the　importance　of　sensitive　detection　methods.　Herein,　a　novel　ternary　composite　material　was　prepared　using　aminopropyl-functionalized　magnesium　phyllosilicate　(AMP),　metal-organic　frameworks　(MOFs)　of　zeolitic　imidazolate　framework-8　(ZIF-8)　and　multi-walled　carbon　nanotubes　(MWCNTs)　through　a　two-step　synthesis　approach.　This　material　was　applied　to　the　sensitive　electrochemical　detection　of　BPA　by　directly　oxidizing　the　target　molecule　at　the　modified　electrode.　The　utilization　of　AMP,　which　suffers　from　poor　aqueous　stability,　was　realized　by　combining　it　with　ZIF-8.　The　introduction　of　MWCNTs　improved　the　conductivity　of　ZIF-8@AMP,　thereby　enhancing　the　detection　performance　of　the　ZIF-8@AMP/MWCNTs　modified　electrode.　Given　the　high　specific　surface　area,　strong　electron　conductivity　and　excellent　stability　of　ZIF-8@AMP/MWCNTs　composites,　BPA　was　detected　with　the　linear　range　(0.04–46.9　μM)　and　the　low　limit　of　detection　(LOD,　3.2　nM).　Moreover,　the　sensor　can　detect　BPA　sensitively　in　tap　water,　lake　water　and　milk　with　recoveries　of　91.9–104.8　%.　In　addition,　this　sensor　also　exhibits　good　reproducibility,　stability　and　selectivity,　firstly　providing　a　new　method　for　the　detection　of　BPA.　©　2025　Elsevier　Ltd
