Arsenic pollution in water primarily occurs in the inorganic forms of As+ and As⁵+, posing significant health hazards even at trace concentrations. Therefore, the continued progress of effective arsenic removal techniques is essential. This review comprehensively explores recent advancements in adsorbent technologies aimed at the treatment of arsenic species from water, addressing a critical global environmental and public health challenge. Adsorption remains one of the most promising arsenic remediation strategies due to its effectiveness, simplicity, and efficacy compared to alternative methods such as membrane filtration, coagulation, ion exchange, and biological treatment. This paper highlights a wide array of adsorbent materials, including mineral materials, activated carbon, metal oxides, polymers, biosorbents, core-shelled, graphene, and industrial by-products, focusing on their adsorption capacities, surface characteristics, and performance under varying conditions, such as pH, removal capacities, surface area, initial ion concentrations, pH, adsorption kinetics, and isotherms. Understanding these factors is vital for evaluating, modifying, and enhancing the adsorption process to address diverse water treatment challenges. Integrating these critical factors into adsorption analysis deepens understanding of its complexities, aiding the development of customized and efficient arsenic treatment methods. The review also emphasizes the importance of optimizing adsorbent regeneration, environmental sustainability, and real-world applications. It concludes with suggestions for future research, calling for the development of more efficient, selective, and eco-friendly adsorbent materials to combat arsenic contamination in water, thereby ensuring safer water sources for affected populations.
