Conversion of agricultural waste products into biochar is regarded as one of several recycling and disposal options.  The study aimed to use biochar from jackfruit waste as an agent for heavy metals removal. Jackfruit waste was selected in this study due to its abundance in Malaysia.  The jackfruit waste was thermally activated by phosphoric acid at 500 oC. Analytical techniques including X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), surface area measurement (BET method), Raman spectroscopy, energy dispersive X-ray (EDX), and fourier transform infrared (FTIR) spectroscopy were used to characterize the synthesized biochars. The physicochemical characteristics of the synthesized biochars were examined using different conditions to determine their usefulness for heavy metals adsorption. The surface morphology of biochars revealed the distributions of numerous cavities, cracks and small pits over the surface with pore size ranged from 3.25 – 3.78 nm. The.....
