Abstract	This paper reports the synthesis of a Jhingan-gum-based hydrogel for the remediation of anionic dyes from water. The synthesized hydrogel was then characterized using several analytical techniques, including elemental analysis, FTIR, XRD, and SEM analyses. Adsorption parameters such as dye concentration, adsorbent dosage, pH, contact time, and temperature were optimized to obtain maximum efficiency. Adsorption studies were carried out, and the experimental data were subjected to various adsorption isotherms, which were best fitted to the Langmuir model (R2= 0.997) with an adsorption capacity of 85.5 mg/g. A kinetic study revealed that the rate of adsorption was best described by a pseudo-second-order model with an R2 value of 0.998. It can be concluded that the rate of adsorption is controlled by chemisorption, which involves chemical interactions between adsorbate and adsorbent. The results of the thermodynamic study suggested that the adsorption process was spontaneous and endothermic, accompanied by an increase in entropy. The hydrogel showed excellent regeneration capacity and biodegradability, with a half-life of 37 days.
