Adsorption is the process of transferring materials from liquid phase to solid phase. In this study, a series of batch laboratory experiments were conducted in order to investigate the feasibility of oil palm trunk fiber (PTF) based inactivated and activated adsorbent for the removal of heavy metals by adsorption process. The influence of contact time, pH, adsorbent dose, initial metal ion concentration and temperature were investigated. The results of were analyzed using langmuir and freundlich isotherm model, freundlich model gave the best fit for Cd (II),Pb (II) and Cr(III) adsorption with regression value R2> 0.9, for both inactivated and activated oil palm trunk fiber adsorbent. The kinetics of the adsorption of Cd(II), Pb(II), Cu (II) and Cr(III), were studied using Pseudo-first-order and Pseudo-second-order. The surface chemical nature of the inactivated and activated adsorbent were studied by Fourier transform infrared spectroscopy (FTIR) which showed functional groups on adsorbent surface.The results showed that palm trunk fiber could be used as an adsorbent for Cd(II), Pb(II), Cu (II) and Cr(III) ions.
