Field　sample　preparation　is　important　and　interesting　for　analysis　of　nitrogen　and　sulfur　containing　aromatic　compounds　(N,S-CACs)　in　environmental　aqueous　samples.　In　this　connection,　a　new　functional　groups-rich　adsorbent　based　on　porous　monolith　(ABM)　was　fabricated　by　in-situ　copolymerization　of　allylaminocarbonylphenyl　boronic　acid/styrene　and　ethylene　glycol　dimethacrylate.　The　prepared　ABM　was　employed　as　the　extraction　medium　of　homemade　portable　multichannel　in-tip　microextraction　device　(PMMD)　for　on-site　entrapment　of　N,S-CACs　in　various　waters.　Because　of　the　abundant　functional　groups,　the　obtained　ABM/PMMD　exhibited　satisfactory　capture　capability　towards　studied　N,S-CACs,　and　the　enrichment　factors　varied　from　454　to　491.　Under　the　optimized　fabrication　conditions,　adsorption　and　desorption　parameters,　the　developed　ABM/PMMD　was　used　to　field　capture　investigated　N,S-CACs　and　followed　by　quantification　with　high　performance　liquid　chromatography.　The　limits　of　detection　were　in　the　ranges　of　0.00030–0.0016　µg/L.　Recoveries　with　low,　medium　and　high　spiked　contents　located　in　the　range　of　82.1–118%　with　good　repeatability　(RSDs　©　2022　Elsevier　B.V.
