چکیده

Maxilon blue (GRL), a widely used dye in various textile industries, has numerous harmful effects on humans, animals, and the environment. Therefore, it is essential to remove these dyes from drinking water to ensure the health and safety of the aquatic environment. In this study, an environmentally friendly and inexpensive hydrogel adsorbent based on gum (GG) with high adsorption efficiency was used. Three types of non-toxic monomers (N-isopropyl acrylamide, itaconic acid, and acrylic acid) were added to remove MB from aqueous solution. The CS-EGDE/TNP composite was characterized by SEM, EDX, TEM, XRD, FTIR, and BET techniques was applied to optimize the adsorption key parameters like contact time (5–60min), concentration of GRL dye (50–300 mg/L), adsorbent dose(0.02–0.08g/L), solution pH (3–10), temperature (10–40°C). The adsorption capacity of hydrogel nanocomposite for GRL dye was 575.55 mg/g at 30°C.  Results supported the potential use of hydrogel nanocomposite as an effective adsorbent for the treatment of cationic dye. Hydrogel can be used as a promising material in many industries to reduce economic costs by regenerating more than four consecutive cycles.
