Tailoring Homogeneous Hydrogel Nanospheres by Facile Ultra-Sonication Assisted Cross-Linked Copolymerization for Rhodamine B Dye Adsorption

The present paper describes the design of shape-oriented hydrogel nanospheres using a facile ultrasonication-supported crosslinked copolymerization technique. effect variable monomer concentration on homogeneity was investigated. chitosan-cl-poly(MMA) were well characterized various techniques such as FTIR, XRD, TGA, SEM, and TEM. studied for their swelling behavior could potentially be used novel adsorbent rhodamine B dye remediation from aqueous media. study found that utilizing nanohydrogel spheres at optimal pH 5 increased RhB adsorption capacity 7.9 to 17.8 mg/g (pH 2 5), followed by slight reduction. Furthermore, when increased, dropped 18.03 2.8 mg/g, but percentage climbed 90.2% 97.8%. At an initial 140 mg/L, achieved 204.3 in 60 min. includes kinetics, isotherm, thermodynamics analyses. interpretation revealed Langmuir isotherms fit best with qmax value 276.26 which is close approximation experimental value, whereas pseudo-second-order kinetics explains process rate. interaction involves multiple forces electrostatic interactions, hydrogen bonding, van der Waals forces, etc.
