Several studies have explored the use of nanoparticles as adsorbents for removing water contaminant, including arsenic, by enhancing the properties of nanoparticles. Nano adsorbents have been identify as promising alternatives to conventional methods for arsenic removal. This study comprehensively reviews existing literature on the effectiveness of nano adsorbents in removing arsenic from polluted water. It assesses the adsorption capabilities of various nanoparticles, considering factors like nanoparticle size, types of nano adsorbents, synthesis methods. The findings indicate a need for further research on appropriate carriers for nano adsorbents to increase permeability and adapt the technology for real-world applications. This review aims to guide readers in selecting suitable nanomaterials and encourage additional research on using nano adsorbents for arsenic removal.
