Copyrolysis of KOH and a Fe-Zn bimetallic oxide to produce functionalized magnetic biochar for effective phenol removal from water

In this study,impregnation combined with KOH activation with different mixing methods was used to prepare magnetic porous biochar.The effects of the synthetic method on the biochar physicochemical properties and adsorption performance were extensively explored.The results showed that treatment of a Fe-Zn oxide with KOH activation provided excellent adsorption properties with adsorption capacity of 458.90 mg/g due to well-developed microporous structure and r…查看全部>>
