Hydrogel for Aqueous Methylene Blue Removal: Natural Rubber/ Poly(ethylene Glycol) Methyl Ether Methacrylate Semi-IPN

Year: 2024

Type: article

Abstract: This study focuses on synthesizing and characterizing a semi-Interpenetrating Network (semi-IPN) elastomeric hydrogel comprising natural rubber (NR) and polyethylene glycol methacrylate (PEGMA) for efficient removal of Methylene Blue (MB) dye from aqueous solutions. The impact of varying PEGMA/NR ratios (100/0 to 0/100) was investigated. SEM images displayed a porous and uniform structure with interconnected pores of different sizes. FTIR analysis confirmed the formation of a semi-IPN structure, showcasing functional groups in both NR and PEGMA. Adsorption studies revealed the hydrogel's efficacy in MB dye removal, achieving a maximum adsorption capacity of 6536 mg/g at a PEGMA/NR ratio of 90/10. UV-vis spectroscopy validated the reduction in MB concentration post-exposure to the hydrogel. These findings highlight the cationic ionic nature of the PEGMA/NR semi-IPN elastomeric hydrogel as a promising adsorbent for MB dye removal in wastewater applications, particularly in industrial wastewater treatment.
