A new green hydrogel consisting of cherry stone (CS) powder and sodium alginate (SA) was synthesized through physical crosslinking. The product had a mean diameter 3.95 mm, moisture content 92.28%, bulk density 0.58 g/cm3, swelling ratio 45.10%. analyses its morphological structure functional groups by scanning electron microscopy (SEM) Fourier-transform infrared spectroscopy (FTIR) showed the successful entrapping CS in SA polymeric matrix. viability prepared as adsorbent tested towards Orange II (OII) anionic dye. influence pH, amount, contact time, initial dye concentration evaluated. Then, impact three accelerating factors (stirring speed, ultrasound exposure duration, temperature) on OII retention investigated. highest recorded removal efficiency adsorption capacity were 82.20% 6.84 mg/g, respectively. followed Elovich pseudo-second-order kinetics, adequately described Freundlich Khan isotherms, can be defined spontaneous, endothermic, random. experiments confirmed that obtained used acceptably for at least two consecutive cycles, sustaining effectiveness water decontamination.
