Development of Azo Dye Immobilized Poly (Glycidyl Methacrylate-Co-Methyl Methacrylate) Polymers Composites as Novel Adsorbents for Water Treatment Applications: Methylene Blue-Polymers Composites

Abstract

Methylene blue azo dye (MB) immobilized onto Poly (glycidyl methacrylate-Co-methyl methacrylate), (PGMA-co-PMMA), and sulphonated Poly (glycidyl methacrylate-Co-methyl methacrylate), (SPGMA-co-PMMA), polymers composites have been developed as novel adsorbents for water treatment applications. The effect of copolymer composition and sulphonation on the MB content has been studied. Maximum MB content was correlated to the Polyglycidyl methacrylate content for both native and sulphonated copolymers. Furthermore, the effect of the adsorption conditions on the MB content was studied. Sulfonated Poly (glycidyl methacrylate; SPGMA) was the most efficient formed composite with the highest MB content. The developed composites’ chemical structure and morphology were characterized using characterization tools such as particle size, FTIR, TGA, and SEM analyses. The developed MB-SPGMA composite adsorbent (27 mg/g), for the first time, was tested for the removal of Cr (VI) ions and Mn (VII) metal ions from dichromate and permanganate contaminated waters under mild adsorption conditions, opening a new field of multiuse of the same adsorbent in the removal of more than one contaminants.

Development of Azo Dye Immobilized Sulfonated Poly (Glycidyl Methacrylate) Polymer Composite as Novel Adsorbents for Water Treatment Applications: Methylene Blue Immobilization Isotherm, Kinetic, Thermodynamic, and Simulations Studies

“…The most dominant is the Freundlich isotherm, which has higher fitness of the adsorption data. This explanation is supported by the data obtained in our previous published study, where the PGMA nanoparticles without and with sulfonation removed 100% of the MB from a 10 ppm solution [ 66 ]. Based on our previous study of the sulfonation conditions, the resulting SPGMA nanoparticles in our current study are partially sulfonated [ 27 ].…”

“…The SPGMA was characterized using FTIR, TGA, and SEM [ 29 ]. The average particle size of SPGMA was 430 nm [ 66 ].…”

“…For the first time, a novel adsorbent for water treatment applications has been created in the first section of our recently published work by immobilizing methylene blue (MB) as the first pollutant onto composites of sulfonated poly(glycidyl methacrylate) (SPGMA) polymers through an adsorption technique. The elimination of metal ions such Cr 6+ and Mn 7+ from dichromate and permanganate-contaminated water, as the second contaminant, has been further studied using the created MB-SPGMA composite [ 66 ].…”
