Abstract

Phosphate recovery from wastewater is vital for both environmental sustainability and resource conservation, offering the dual benefit of reducing phosphate pollution while providing a valuable source of this essential nutrient. We previously reported an approach for synthesizing hydrous manganese oxide (HMO) nanoparticles within a polymeric cation-exchange membrane (CEM) to achieve a phosphate-selective mixed-matrix membrane (PhSMMM); however, the phosphate flux was lower than desired. Herein, we demonstrate a next-generation PhSMMM membrane with enhanced phosphate flux and selectivity. Experimental results confirm the successful incorporation of up to 28 wt% HMO nanoparticles into the polymeric CEM. The new PhSMMM exhibits a phosphate flux of 1.57 mmol∙m–2.hr–1 (an 8.5X enhancement), with selectivity over chloride, nitrate, and sulfate ions of 9, 11, and 104, respectively. This significant enhancement in phosphate flux marks a promising advancement in a sustainable solution for phosphate removal and recovery from wastewater.

通过单离子反向选择混合基质阳离子交换膜提高磷酸盐阴离子通量
从废水中回收磷酸盐对环境的可持续发展和资源保护都至关重要,既能减少磷酸盐污染,又能提供这种重要营养物质的宝贵来源,一举两得。我们曾报道过一种在聚合物阳离子交换膜(CEM)中合成氧化锰(HMO)纳米颗粒的方法,以实现磷酸盐选择性混合基质膜(PHSMMM);然而,磷酸盐通量低于预期。在此,我们展示了具有更高磷酸盐通量和选择性的新一代 PhSMMM 膜。实验结果证实,在聚合物 CEM 中成功加入了高达 28 wt% 的 HMO 纳米颗粒。新型 PhSMMM 的磷酸盐通量为 1.57 mmol∙m-2.hr-1 (提高了 8.5 倍),对氯离子、硝酸根离子和硫酸根离子的选择性分别为 9、11 和 104。磷酸盐通量的显著提高标志着在从废水中去除和回收磷酸盐的可持续解决方案方面取得了可喜的进展。
