Coffee residue-based activated carbons for phenol removal

This work was aimed to evaluate the adsorptive properties of activated carbons from coffee residue for phenol removal. The coffee residue was activated using H3 PO4 and KOH, and the resultant activated carbons were characterized for surface area and functional groups. The values of surface area were...
