Iron and nitrogen co-doped biochar membrane for SMX removal in water by filtration and catalytic oxidation
Iron and nitrogen co-doped biochar membrane (Fe/N/BC membrane) was fabricated. Epoxy resin was used as a binder, 4,4́-diaminodiphenylmethane as curing agent, and polyethylpyrrolidone as pore-making agent, respectively. The Fe/N/BC membrane showed excellent performance of filtration and catalytic oxidative removal of sulfamethoxazole (SMX) in water and its water flux was 127 L·m−2·h−1·bar−1. The Fe/N/BC membrane had a good application prospect in a wide pH range (both acidic and neutral conditions). The contribution of Fe doping was higher than that of N doping in the SO4• − and ·OH radicals generation pathways but the contribution of N doping is higher than that of Fe doping for the 1O2 non-radical generation pathway. Finally, the membrane facilitates the recovery of catalytic materials and solves the problem of secondary pollution to the environment. This study provides an important practical prospect for efficient and rapid removal of SMX in water.
期刊介绍：
Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
