A new kind of magnetic functional nano-adsorbable material Fe3O4@ g-C3N4 was prepared by deposition reduction method ,w hich is better in the evaluation of the adsorption performance to ura-nium S.ome characterizations results were used to show that the g-C3N4 particles is wrapped around the magnetic Fe3O4 nano particles ,and the physical structure of the adsorbed material is improved ,so the adsorption performance of uranium is better .Adsorption experiments were used to show that the best pH value is 10 ,the best dosage of adsorbent is 6.5 mg and the optimum adsorption time is 150 min in the 140 mg/L uranium-contained solution system ,the maximum adsorption capacity is up to 352.1 mg/g and the best adsorption rate can reach to 90% .%利用沉积还原法制备了一种新型磁性功能纳米吸附材料Fe3O4@g-C3N4并应用于铀的吸附性实验中,获得了较好的吸附性能评价.表征方法表明,材料g-C3N4包裹在磁性Fe3O4纳米粒子的外部,其吸附材料物理组织结构得到提升,吸附铀的性能较好.吸附实验表明,在质量浓度为140 mg/L的铀标准溶液中,最佳的pH值为10,最佳的吸附剂投入量为6.5mg,最佳吸附时间为150min,最大吸附量可达352.1 mg/g,最佳吸附率可达到90%以上.
