Abstract: A novel phosphate surface-imprinted polymer (GO-IIP) with high performance has been prepared by developing a La(III)-coordinated 3-methacryloxyethyl-propyl (MPS) bi-functionalized graphene oxide (GO). La(III) modified graphene oxide (GO-La) was used as functional monomer and methyl methacrylate (MMA) was used as auxiliary functional monomer. The synthesized GO-IIP exhibited higher adsorption capacity and outstanding selectivity and recognition for the binding of phosphate than GO-NIP. The equilibrium adsorption isotherms can be well fitted by the Langmuir model and the maximum adsorption capacity was higher as 104.3 mg/g at 25 °C. The results showed that GO-IIP exhibited excellent selectivity, good reusability and could be an ideal adsorbent for removing phosphate from wastewater
