The present invention discloses an adsorbent composition of chitosan reinforced mixed oxide granular nanocomposite for water-related applications, specifically for water purification. The granular nanocomposite comprises active ingredients homogenized in the aggregated network of chitosan templated aluminum oxyhydroxide/2-line iron oxyhydroxide composite. The composition is versatile as any metal or non-metal ion (including transition metals and/or rare earth metals) can be used. The composition itself can be a water purifier, such as an adsorbent for fluoride and arsenic removal from water with excessively high fluoride and arsenic adsorption capacity.
