摘　　要：In view of widespread existence and toxicity,removal and detection of bisphenols is imperative to asses environmental risks and reduce harm to human health.Although many techniques have been reported constructing fast and sensitive method remains a challenge.Herein,porous poly(divinylbenzene)polyme was synthesized in-situ on the Fe_(3)O_(4)particles by means of distillation-precipitation polymerization and functioned as sorbents to extract bisphenols.Employing Fe_(3)O_(4)@poly(divinylbenzene)as sorbent,a mag netic solid-phase extraction coupling with liquid chromatography was developed to detect trace bisphe nols in water.This method presented low detection limits(0.01–0.03 ng/m L),high enrichment ability(en richment factor,327–343),and good reproducibility.Moreover,the method showed satisfactory recoverie in the detection of lake water(80.60%-116.2%)and egg sample(75.17%-120.0%).Impressively,Fe_(3)O_(4)@PDVB has excellent adsorption capacity,which can realize rapid kinetic adsorption of bisphenols with equi librium time all less than 10 s.The maximum adsorption capacities reached 1074.8,1049.7,1299.1 and 1329.5 mg/g for bisphenol F,bisphenol A,bisphenol B and bisphenol AF with Langmuir isotherm model The adsorption mechanism of Fe_(3)O_(4)@PDVB to bisphenols was investigated and demonstrated that hy drophobic interactions played a key role,together with assistance ofπ-πstacking interactions and hy drogen interactions.Overall,this work provides a promising sorbent material with ultra-fast and large adsorption capacities for extraction of bisphenols from water.
