Microwave-assisted H3PO4 chemical activation was applied to convert corn (Zea mays) cob (CC) residue into mesoporous corn cob activated carbon (CC-AC) as a desirable adsorbent for cationic dye (methylene blue; MB) removal. The activation process was carried out by impregnating CC with phosphoric aci...
