Abstract
Lead (II) ions are a very toxic element known to cause detrimental effects to human healtheven at very low concentrations. An adsorbent prepared using Cane Papyrus was used for theadsorption of lead (II) ion from aqueous solution. Batch experiments were performed onsimulated aqueous solutions under optimized conditions of adsorbent dosage, contact time, pHand initial lead (II) ion concentration at 25Co. The Freundlich isotherm model more suitablydescribed the adsorption process than the Langmuir model with linearized coefficients of 0.986and 0.9733, respectively. Pseudo-second order kinetic equation best described the kinetics of thereaction. Fourier transform infra-red analysis confirmed the presence of amino (–NH), carbonyl(–C=O) and hydroxyl (–OH) functional groups. Furthermore, 0.2M HCl was a better desorbingagent than 0.2 M NaOH and de-ionized water. The experimental data obtained demonstrated thatCane Papyrus can be used as a suitable adsorbent for lead (II) ions removal from wastewater.
