High surface area functionalized carbon briquettes: a novel adsorbent for contaminants from water

In this work, the advantages of special briquette shape and high surface area functionalized carbon were combined to produce a novel adsorbent for metals. BET, TG, IR, acid site and EDS analyses suggest that the functionalization with HNO3 and metal adsorption takes place throughout the briquette bo...

Zusammenfassung:In this work, the advantages of special briquette shape and high surface area functionalized carbon were combined to produce a novel adsorbent for metals. BET, TG, IR, acid site and EDS analyses suggest that the functionalization with HNO3 and metal adsorption takes place throughout the briquette body. The adsorption isotherms and kinetics have been studied for Cr3+, Zn2+ and the dye methylene blue.
