The iron - lanthanum mixed oxyhydroxide (FLMOH) and chitosan engraved iron - lanthanum mixed oxyhydroxide materials (CSFLMOH) were prepared successfully and utilized for the hexavalent chromium adsorption studies. The physicochemical properties of pristine and Cr(VI) treated adsorbents were characterized using XRD, FTIR, SEM with EDX, TGA and DSC analysis. The efficacy of the CSFLMOH was compared with FLMOH towards the uptake of Cr(VI) ions and was explored using batch technique under various influencing parameters viz., time, dose, pH, initial concentration and co-existing anions. Langmuir, Freundlich and Dubinin - Radushkevich isotherms were used to analyze the adsorption behavior at 303, 313 and 323 K. The rate of the reaction was calculated using reaction based and diffusion-based models. Recycle and reuse studies were demonstrated using 0.05 M NaOH as the desorbing medium.
