Adsorption of Zn from aqueous solution by activated carbon derived empty fruit bunches: Statistical approach

Oil palm (OP) industry in Malaysia produces about 40 million tones of oil palm biomass containing empty fruit bunches (EFB), trunks, fronds, fiber and fruit shell. The EFB represents about 10% of the total by-products generated which is either left in the plantation to provide organic nutrients to t...
