The design of absorbents to remove toxic dyes has made significant progress. Absorbents based on polymer composites are important with diverse potential applications. The use of natural chitosan polymer as the continuous phase of composite has been expanded due to its biocompatibility, biodegradability, and distinctive properties. In this research, the absorbent based on chitosan composite containing montmorillonite (MMT) clay and egg shell inspired by nature was used to remove methylene blue (MB) dye from aqueous solution. The ratios of 0.25, 0.5 and 0.75 g of clay and eggshell absorbent in chitosan composite were used to remove the dye after immersion in aqueous medium. The proportion of 0.25 g was chosen as the optimal sample based on the results of the maximum removal. The amount of dye removal was evaluated by the final composite as the optimal sample in the concentration of 15 ppm of methylene blue pollutant and 0.25 g/l of absorbent by the final composite. Samples were investigated by dynamic light scattering (DLS) to examine size and size distribution, scanning electron microscope (SEM) and transmission electron microscope (TEM) to evaluate shape and size, energy dispersive spectroscopy (EDS) for chemical spectroscopy analysis, Fourier transform infrared (FTIR) to determine functional groups, X-ray diffraction (XRD) to check the crystal structure, BET analysis to measure the surface area, and UV-vis spectrophotometer to study the amount removal. Based on the results of the chitosan composite containing 0.25 g of clay and eggshell as the optimal sample, it showed the highest (94%) removal of methylene blue dye from the aqueous solution.
