Abstract:
The carbon substance known as "activated carbon" has a very porous, amorphous structure. They can adsorb organic pollutants and heavy metals thanks to its active surface. In the current study, Lantana camara was impregnated with orthophosphoric acid using a 1:1 impregnation ratio to produce activated carbon utilizing a chemical activation approach. With an activation time of one hour, the activation temperatures employed were 500 °C, 550 °C, 600 °C, 650 °C, and 700 °C.This study shows that, while the adsorption capacity of activated carbon increases with increased activation temperature, activated carbon synthesis decreases as activation temperature rises. According to this study, the highest amount of iodine adsorption occurs when activated carbon is formed at an activation temperature of 700 °C.
