AB  - In this study, Montmorillonite/Carrageenan (MMT/CG)-composite hydrogel was synthesized for removal of Chromium (VI) from aqueous solution. The chemical structure, morphological property and thermal decomposition of (MMT/CG)-composite hydrogel has been evaluated by Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscope Spectroscopy (SEM) and thermogravimetric analysis (TGA), respectively. The X-ray data of (MMT/CG)-composite hydrogel was researched crystallite properties. The results of (MMT/CG)-composite hydrogel CG, and MMT powders had compared each other to research the efficiency of MMT. The efficiency of adsorption parameters (contact time, initial feed concentration, and pH) on Chromium (VI) ion adsorbing capacity of (MMT/CG)-composite hydrogel was also investigated by UV–vis diffusive reflectance spectra. The adsorption capacity enhanced with the adding of MMT in hydrogel. The adsorption process was determined by the Langmuir isotherm model. According to the findings, the MMT/CG-composite hydrogel can be utilized as a suitable adsorbent to removal of Chromium (VI) from aqueous solution.
