Variation in Metal Removal from Contaminated Water Using Activated Charcoal, Charred and Uncharred Plant Materials, Eggshells and Oxalic Acid

In today’s economy, determining accessible and affordable techniques to remove Heavy Metals (HMs) from wastewater is crucial. Activated carbon is highly effective in adsorbing HMs due to its large surface area and porous structure. It works by attracting and binding HM ions to its surface. Okoubaka is known for its medicinal properties and some studies suggest it has detoxifying effects. However, its specific role in HM removal would likely involve binding mechanisms like other plant-based materials. This study examines the efficiency of activated charcoal, charred versus uncharred Okoubaka plant materials, eggshells and oxalic acid to remove HMs like copper, lead, and zinc from contaminated water.
