Mercury Removal by Biochar and Activated Carbon: An Effective Approach for Environmental Remediation

Mercury (Hg) contamination is a pressing environmental issue due to its persistence, bioaccumulation, and toxicity. In recent years, biochar and activated carbon have emerged as effective adsorbents for mercury removal. This article provides an overview of the use of biochar and activated carbon in mercury remediation and highlights their adsorption mechanisms. The potential of various biochar and activated carbon materials, including modified versions, for mercury removal from water, soil, and air is discussed. The regeneration and reusability of these adsorbents are also explored. The findings suggest that biochar and activated carbon offer a sustainable and efficient approach to addressing mercury contamination.
