Abstract

Contaminated water resources especially with heavy metals and dyes from industrial processes pose a real threat to long-term and sustainable global development i.e., clean, and safe water, and sustainable communities. Activated carbon (AC) synthesis from degradable and non-degradable resources, their activation and modification to advanced and efficient material has been a target area of modern research work due to their distinguished properties such as enhanced surface area, porosity, and surface chemistry. This review briefly describes the recent advancements in the development of modified AC, adsorption isotherms and kinetics, and their mechanism according to the nature of pollutant present in wastewater. Also, the most significant parameters affecting the activation/modification and adsorption process are discussed. Although, the modified AC can achieve tremendous adsorption capacity, removal efficiency, but the modification process is complex, and their applications are only limited to batch levels. Most research should be focused on the development of simple, cost-effective technical approach for AC synthesis more specifically from non- degradable resources concerning the environmental problems, and further studies on real wastewater system are essential. This review highlights the wastewater treatment applications (heavy metals and dyes) of AC as adsorbent using adsorption technology, critically pinpoints the research gaps and suggestions for future.
