Palygorskite-based polymer microspheres (PMs) have been synthesized through Pickering emulsion polymerization, characterized and applied for the adsorption of I − anions. The adsorption capacity of PMs can reach up to 1.20 mmol/g within only 5 min. Moreover, PMs possess an excellent reusability with an iodide adsorption efficiency of 87.1% after five cycles. pH shows a significant influence on the iodide adsorption, but underground water or river water has a little effect. Based on these findings, the resulting PMs show great in the capture and enrichment of iodide from wastewaters through a green, environmentally friendly, and sustainable way.

绿色低成本坡缕石基微球快速可逆吸附废水中的放射性碘

坡缕石基聚合物微球 (PMs) 已通过 Pickering 乳液聚合合成，表征并应用于吸附 I - 阴离子。PMs 的吸附容量可在 5 分钟内达到 1.20 mmol/g。此外，PMs 具有优异的重复使用性，五次循环后碘化物吸附效率为 87.1%。pH值对碘化物的吸附有显着影响，但地下水或河水影响不大。基于这些发现，由此产生的 PMs 在通过绿色、环保和可持续的方式从废水中捕获和富集碘方面表现出色。
