ABSTRACT

The present study explored the ability of Curry Tree Carbon (CTC) for removal of Zn(II) ionsin aqueous solution. Batch experiments were conducted. The sorbent, which was prepared by a simple and concise method, was able to bind heavy metal viz., Zn(II) ions with very high efficiencies. The adsorption study was confirmed through characterization tests such as Fourier transform infrared spectroscopy X-ray diffraction analyses, scanning electron microscopy and elemental analysis. The CTC showed considerable capacity for removal of Zn(II) ions from aqueous solution. The Langmuirisothermmodelfittedwelltoexperimental metal sorption. In this study, the sorption mechanism and ionexchange seem tobe the most occurring phenomena.

Keywords: CTC, Batch experiments, isotherm modeling, kinetic modeling.
