The current research investigates the adsorption properties of a chemically crosslinked hydrogel based on sodium alginate and carboxymethyl cellulose. The investigated hydrogel's physical characteristics are described in detail by Fourier Transform u2013infrared spectra, Xu2010ray diffraction traces, and field emission scanning electron microscopy photographs. According to the kinetic experiments, the decolorization equilibrium of SO by NaALG/ECH/CMC was found in 4 hours, while NaALG/ECH/CMC's removal of BG required 6 hours. Absorption of NaALG/ECH/CMC hydrogel was shown to take place in monolayer adsorption form. The highest adsorption capacity for BG was found to be 864. 8 mg gu22121, and SO it was 193. 1 mg gu22121, by synthesised hydrogel, where u201d refers to the commercial colourant rather than the pure dye. The synthesised hydrogel, therefore, can be used as a useful instrument for dye adsorption in water purification tasks.
