Seaweed-Derived Hierarchically Porous Carbon for Highly Efficient Removal of Tetracycline
文献摘要：
Herein we present a facile approach for the preparation of a novel hier-archically porous carbon,in which seaweeds serve as carbon source and KOH as activator.The fabricated KOH-activated seaweed carbon(K-SC)displays strong affinity towards tetracycline with maximum uptake quantity of 853.3 mg/g,significantly higher than other tetracycline adsorbents.The supe-rior adsorption capacity ascribes to large specific surface area(2614 m2/g)and hierarchically porous structure of K-SC,along with strong π-πinteractions between tetracycline and K-SC.In addition,the as-prepared K-SC exhibits fast adsorption kinetics,capable of removing 99％of tetracycline in 30 min.Meanwhile,the exhausted K-SC can be regenerated for four cycling adsorption without an obvious degradation in capacities.More importantly,pH and ionic strengths barely affect the adsorption performance of K-SC,implying electrostatic in-teractions hardly play any role in tetracycline adsorption process.Furthermore,the K-SC packed fixed-bed column(0.1 g of adsorbents)can continually treat 2780 mL solution spiked with 5.0 mg/g tetracycline before reaching the breakthrough point.All in all,the fabricated K-SC equips with high adsorption capacity,fast adsorption rate,glorious anti-interference capability and good reusability,which make it hold great feasibilities for treating tetracycline contamination in real applications.
