| dc.description.abstract | Lead (Pb(11)) has been widely reported as a major environmental contaminants. Lead is recalcitrant, capable of forming complexes and bio-accumulate in the tissues of plant and animals. A number of adsorbent media and adsorption treatment techniques have been adopted to effect lead removal from wastewater. However, this study reported the decontamination of vegetable oil impacted wastewater containing Pb(II) by dynamic adsorption process using fixed column bed of plantain peel activated carbon(PPAC and bamboo activated carbon(BAC). Pb(II) adsorption Uptake performance of PPAC and BAC bed materials were represented on various breakthrough curves. Uptake capacity of Pb(II) was more phenomenal in PPAC bed material than on BAC. Column Adsorption removal efficiency of various bed materials was assessed at 50% breakthrough with efficiency of removal at 45-50%. In the case of mass transfer, film diffusion played leading roles on the mass transfer of Pb(II) to PPAC bed material. Internal and Kundsen diffusion played significant role on mass transfer of Pb(II) to BAC due to its supposed large pore sizes. Thomas, Yoon-Nelson, Adams-Bohart and Bed depth service time (BDST) models were applied to study the kinetics of adsorption dynamic of Pb(II) onto the bed materials. The models reasonably fitted the data, however the compliance of the models to the data is stated as follows; BDST Thomas>Yoon-Nelson>Adams-Bohart. Breakthrough and bed service times of PPAC and BAC materials assessed at various saturation levels progressed as percentage of saturation moved from 20% to 90% through 60%. PPAC and BAC reasonably removed Pb(II) ion from vegetable oil polluted wastewater through dynamic adsorption proce | |
