The study focused on developing two types of nanocomposites made from chitosan, itaconic acid, and bentonite for effectively removing methylene blue dye from water.
Maximum dye adsorption occurred at pH levels 6 and 7 for the two different nanocomposites, with the highest capacity for the modified version (CTS-g-IA/BT).
The adsorption process was spontaneous and endothermic, fitting well with the pseudo-second-order kinetic model and Langmuir isotherm, indicating efficient dye removal capabilities of the synthesized nanocomposites.
