Adsorption and removal of chromium (VI) contained in aqueous solutions using a chitosan-based hydrogel

The aim of this work was to study the adsorption and removal of chromium (VI) ions contained in aqueous solutions using a chitosan-based hydrogel synthesized via chemical crosslinking of radical chitosan, polyacrylic acid, and N , N ′-methylenebisacrylamide. Fourier-transform infrared spectroscopy c...
