A novel surface-ion-imprinted polymer (IIP) was prepared using As(III) as template, and Fe₃O₄/GO as support. Adsorption behavior was studied. The fitted maximum adsorption capacity of MGO-As(III)-IIP was 49.42 mg/g.MGO-As(III)-IIP showed stable dispersive properties and great reusability in solution with an adsorption efficiency of 75% after five cycles of regeneration and reuse. MGO-As(III)-IIP indicated high selectivity under the presence of other competitive components. The binding characteristics of imprinted polymers were evaluated with the Scatchard model. Simulated column experiments with different material concentrations showed the effect of the sustained adsorption of As(III) in aquifers and the migration and residue of MGO-As(III)-IIP under external magnetic field. The adsorption effects of MGO-As(III)-IIP on 10 PV arsenic-contaminated water with a concentration of 2 mg/L were 49.76%, 68.57%, 80.74%, and 84.54%, and the recycling efficiency reached 27.1%, 34.5%, 41.1%, and 49.8%. Compared with the previous materials, the removal efficiency is greatly improved. MGO-As(III)-IIP has great potential to be used as a mobile and recyclable material for in-situ treatment of As(III) in groundwater.

以As（III）为模板，Fe ₃ O ₄ / GO为载体，制备了一种新型的表面离子印迹聚合物（IIP）。研究了吸附行为。MGO-As（III）-IIP的拟合最大吸附容量为49.42 mg / g.MGO-As（III）-IIP在经过五个再生和再利用循环后显示出稳定的分散性和良好的可重复使用性，在溶液中的吸附效率为75％。MGO-As（III）-IIP表明在存在其他竞争性组分的情况下具有高选择性。印迹聚合物的结合特性用Scatchard模型评估。不同材料浓度的模拟柱实验表明，在外部磁场下，As（III）在含水层中的持续吸附以及MGO-As（III）-IIP的迁移和残留的影响。MGO-As（III）-IIP对10种浓度为2的PV砷污染的水的吸附作用 mg / L分别为49.76％，68.57％，80.74％和84.54％，回收效率分别达到27.1％，34.5％，41.1％和49.8％。与以前的材料相比，去除效率大大提高。MGO-As（III）-IIP具有巨大的潜力，可作为可移动和可回收的材料用于地下水中As（III）的原位处理。
