Regeneration of Spent Activated Carbon Using H2SO4, HCl and H2O2

Abstract

The regeneration of spent activated carbon (AC) offers a practical solution to environmental and economic challenges associated with its saturation and disposal. This study investigates the chemical regeneration of spent AC using three agents, sulfuric acid (H₂SO₄), hydrochloric acid (HCl), and hydrogen peroxide (H₂O₂). Activated carbon, renowned for its high adsorption capacity owing to its large surface area and porous structure, is widely utilized in water purification, air filtration, and industrial applications. However, the saturation of adsorption sites compromises its efficiency, necessitating effective regeneration processes to restore its functionality and reduce waste generation.
