主　　题：Amino-functionalization Porous polydivinylbenzene(PDVB) Adsorption Regeneration Fluoride anion 

摘      要：Excessive fluoride anions in drinking water are toxic to the health of human *** this article,an effective fluoride removal adsorbent on the basis of amino-functionalized porous polydivinylbenzene(PDVB)was prepared through low cost processes,which included solvothermal preparation of porous PDVB and subsequent surface *** obtained amino-functionalized porous PDVB(A-PDVB)has high surface area of 443 m2 g1 and high adsorption capacity towards fluoride anion up to 105.9 mg *** adsorbents surface area,the adsorption capacity per unit surface area of A-PDVB is 0.24 mg m2 which is more than 4 times of porous PDVB(0.058 mg m2).The enhanced adsorption performance of A-PDVB was due to amino groups electrostatic interaction coupled with hydrogen bond binding with fluoride *** addition,the aminofunctionalized porous PDVB could be regenerated in high efficiency under alkaline *** work not only exhibits the possibility of A-PDVB for application as an environment-friendly adsorbent for fluoride removal but also gives an insight into understanding mechanism of the fluoride anions adsorption onto aminofunctionalized porous PDVB.
