Kenaf (Hibiscus cannabinus) is a hardy crop that has wide industrial applications such as insulator, paper, carpet padding, bedding and a good adsorbent for oil. This study investigated the ability of carbon disulfide (CS2) modified kenaf (CMK) to remove toxic Pb (II) from waste water. Adsorbent characterization was carried out by Field Emission Scanning Electron Microscope and Energy Dispersive X-ray Spectroscope (FESEM-EDX) analysis. The adsorption kinetic data was well described by pseudo-second-order model and the adsorption isotherm study indicated that Langmuir model fitted well with the experimental data than the Freundlich model. Based on the Langmuir model, the maximum adsorption capacities of Pb (II) (qmax) was 63.3 mg g-1 .This study suggested that CMK has a good potential to be used as an adsorbent material for Pb (II) removal from aqueous solutions. |
