Carboxymethyl cellulose-assisted reforming of poly (acrylic acid-co-methyl methacrylate) for boost removal of dyeing wastewater and improved stabilization of Ag nanoparticles to eradicate microbes

Abstract

In this study, the conventional fibrous structure of poly (acrylic acid-co-methyl methacrylate) chains is reoriented and significantly joined to form a layer-like morphology by being hybridized with carboxymethyl cellulose. Such innovative hybrid polymeric material is analyzed using various techniques, including, FTIR, XRD, swelling and contact angle studies, DLS, AFM, and SEM. Removal efficiency of such hybrid polymeric system is scrutinized in treatment of dyeing wastewater. Removal of cationic safranin dye from wastewater is best described by Langmuir model and pseudo-first-order kinetic approach, adopting exothermic adsorption progression with highly developed capacity (~ 59.47 mg/g) and accelerated rate (~ 1.06 h− 1). Such hybrid polymeric system exhibits elevated removal efficiency of ca. 90% within 10 min for at least five-consecutive cycles. Besides, such hybrid polymeric system considers a potential platform to stabilize Ag nanoparticles upgrading their accessibility to eradicate Escherichia coli and Staphylococcus aureus bacteria. Increased demand for exploring innovative materials in the field of wastewater treatment requalifies the hybrid O-rich polymeric systems to a magnificent adsorbing and biocidal performance.
