Abstract
As one of the largest oil palm producers in the world, Malaysia also produces the most abundant residues of palm oil known as empty fruit bunch (EFB). Mismanaging of this residue such as being unused and disposed to sanitary landfills will put the environments in danger. Hence, modification and environmental application of EFB for the pollutant removal is a hot research topic in recent trend. This study involves modification of palm oil industrial residues as EFB-activated carbon and further used as an adsorbent for the removal of lead. The physicochemical property of the EFB-activated carbon was assessed using SEM, FTIR and BET. The adsorption conditions i.e., pH, adsorbent dose, and contact time for the effective removal of lead were optimized. The optimum reaction conditions for lead adsorption by the EFB-activated carbon were 10 g/L of adsorbent, pH 1.0 and 15 min as contact time for the effective removal of lead in aqueous solution. The maximum lead concentration that has removed successfully was 92.24 mg/L under the optimum condition. This study may provide solution to manage the EFB residuals generated from palm oil industries and lead contaminated in the aquatic environment. • EFB-activated carbon was prepared from oil palm industry residuals for lead removal. • The surface area of EFB-activated carbon was found to be 374.73 m 2 /g. • The maximum lead removal was 92.24 mg/10 mg of EFB-activated carbon. • The EFB-activated carbon is a good adsorbent for lead removal from aqueous solution. • This study provides a way to reuse the oil palm solid waste for pollutant removal.
