What is Cationic Dye Removal Using Hydrogels about?
This document summarizes a study on using poly(acrylamide-co-acrylic acid) hydrogels to remove cationic dyes from aqueous solutions. Key points: - Poly(acrylamide-co-acrylic acid) hydrogels were prepared via gamma irradiation and used to study swelling, diffusion, and uptake of cationic dyes like Safranine-O and Magenta. - The maximum swelling observed of the hydrogels in water and dye solutions was 2700-4000%. Diffusion of water and dyes in the hydrogels was non-Fickian. - Adsorption of the cationic
