Revolutionizing arsenic contaminant mitigation: Cutting-edge advances in adsorption technique: An Essence Review

Arsenic contamination in aqueous environments is a critical global challenge, demanding innovative and sustainable solutions. This review comprehensively studies various arsenic toxicities to the environment and their removal techniques. To start with, the manuscript focuses on the background of arsenic existence, its harmful health effects, and its determination techniques. In addition, this review also gives a detail discussion on how arsenic can be removed from the environment by different methods like adsorption, ion exchange, precipitaion, chemical precipitaion, coagulation, and phytoremediation and in the end the advantages and disadvantages of these methods. The low cost, easy to use and simplicity of adsorption technique and the use of novel adsorbents like bioadsorbents, graphenes and nanomaterials are better future alternatives for arsenic removal. According to the available data, when using bioadsorbents for the removal of arsenic the pH ranges from 6- 8 for trivalent arsenic and 6–9 for pentavalent arsenic with the adsorption capacity ranges form 1– 30 mg/g for trivalent and 1–86 mg/g for pentavalent arsenic and when using graphene based adsorbents for the same purpose then for trivalent and pentavalent arsenic pH ranges from 4–7 and amount adsorbed was in the range 64–147 mg/g and 12- 113 mg/g
