Physicochemical properties of chemically activated empty fruit bunch biochars and their sorption capacities for pentachlorophenol as compared to a commercial activated carbon

Chemical modification has been used to produce biochar composites with enhanced surface properties to adsorb organic contaminants efficiently. In the present study, the effectiveness of an empty fruit bunch biochar (EFBB) activated with hydrochloric acid (A-EFBB), sodium hydroxide (B-EFBB) and iron...
