This study of Matamba shell reviled them as material with outstanding surface morphology, elemental and kinetic mechanism characteristics. Mutamba biochar revealed irregular honeycomb morphological transformation from the field emission scanning electron microscope after pyrolysis at 600 °C for 2 h. Energy dispersive X-ray spectroscopy revealed high content of carbon (72.68wt%), nitrogen (14.14wt%) and oxygen (10.35wt%) on the biochar surface. The available oxygen composition provides enough polarization ability for high iodine adsorption (43.65 mmol/g) from the experimental data which were significantly induced by weak van der Waals forces and π-π and π-stacking interaction on the biochar surface and its micropores. The carbon content above 50% in ash rich biochar with an increase in pyrolysis can be ascribed to elements incorporated into aromatic or heterocyclic ring system established …
