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.

通过开发La（III）配位的3-甲基丙烯酰氧基乙基-丙基（MPS）双功能氧化石墨烯（GO），已经制备了具有高性能的新型磷酸盐表面压印聚合物（GO-IIP）。La（III）改性氧化石墨烯（GO-La）被用作功能单体，甲基丙烯酸甲酯（MMA）被用作辅助功能单体。合成的GO-IIP与GO-NIP相比，具有更高的吸附能力，出色的选择性和对磷酸盐的结合识别。Langmuir模型可以很好地拟合平衡吸附等温线，并且在25°C时最大吸附容量更高，为104.3 mg / g℃。结果表明，GO-IIP选择性好，可重复使用性好，是去除废水中磷酸盐的理想吸附剂。
