Abstract

Oil palm empty-fruit bunches (OPEB) bio-sorbent were modified by introducing phosphate(P) into the OPEB-cellulose structure (P-OPEB). This modification effect to increasing the surface area in purpose to enhancing the adsorption amount. Adsorption of Zn(II) was keeping the optimum adsorption by P-OPEB is higher than Fe(II). On the other hand, by using OPEB bio-sorbent, Fe(II) was adsorbed higher than Zn(II), but the adsorption amount by P-OPEB is higher than OPEB which indicated phosphate modified was effected to increasing the adsorption capability of OPEB. The properties of all adsorption systems are similar, refer to the Langmuir model, and kinetic models refer to the 2nd-order kinetics model, but Fe(II) adsorption fits better with the OPEB bio-sorbent. Besides being able to increase the adsorption capacity, P-OPEB also makes the adsorption process faster so that can be more efficient to remove Fe and Zn contaminants.
