摘要: Abstract Bentonite clay, chitosan and acrylic copolymer gels have been separately reported for the adsorption of dyes. In present work these three kinds adsorbents were combined to make composite hydrogels. The hydrogels characterized by FTIR, XRD, DTA–TGA SEM. swelling, diffusion network parameters also evaluated. These used removal malachite green methyl violet dyes from water. showed high removal% both mass transfer coefficient, coefficient thermodynamic dye determined.
