This research aimed to evaluate the potential of coconut tree sawdust (CTS), eggshell (ES) and sugarcane bagasse (SB) to immobilise metals in contaminated soil. This research is divided into three parts, namely characterisation studies, adsorption studies and pot experiments. The characterisation studies of amendment agents were performed using Scanning Electron Microscope (SEM), Energy Dispersive X-ray (EDX) Spectrometer and Fourier Transform Infrared (FTIR) Spectrometer. The characterisation studies were conducted to identify the effects of metal ion binding on the surface morphology of the amendment agents, to confirm the presence of functional groups in the amendment agents and to elucidate the possible binding mechanism. The SEM images showed that the surface morphology of the amendment agents changed significantly following interaction with metal. Meanwhile, the EDX spectra confirmed the presence of metal on the surface of the amendment agents after adsorption process. The FTIR s.....
