Removal of Zn and Cu from Wastewater by Sorption on Oil Palm Tree-Derived Biomasses

B. Salamatinia, A.H. Kamaruddin and A.Z. Abdullah
In this study Oil Palm Bark (OPB), Oil Palm Frond (OPF) and Empty Fruit Bunch (EFB) were evaluated as low-cost sorbent materials for removal of Cu and Zn from water in a batch mode. All the biomasses were used without any chemical modification to evaluate their initial sorption capacity. The sorption processes were performed in a batch mode with 250 mL Cu and Zn solutions at 100 mg L-1 using between 0.5 and 1.0 g of sorbent. The samples were tested every 24 h up to 168 h in normal room temperature. No diffusion limitation was observed in the sorption process. A Zn removal efficiency of 51.5 and 46.0% with 1.0 of OPF and EFB, respectively was observed while OPB showed the lowest removal efficiency. For Cu, the removal achieved was 54% for 1.0 g OPF and 56.5% using 1.0 g of EFB. Cu showed better sorption on the three biomasses. The OPB and EFB introduced excessive amounts of soluble organics into the water. The experimental data obtained with OPF sorbent could fit Freundlich isotherm model better with R2>0.99. This result suggested the heterogeneous binding sites in the biomass.
