چکیده
A new environmentally acceptable method for manufacturing high carboxyl content (CC) oxidized cotton waste (OCW) utilizing H2O2/NaOH has been developed. A fully bleached cotton waste was preserved with alkali hydrogen peroxide in the attendance of sodium hydroxide to increase the surface area and pore size of cotton waste (CW) due to removing hemicellulose, lignin, and impurities and then treated chemically to produce free radicals from oxidized waste cotton by hydrogen peroxide. The structure and morphology of the resulting OCW were meticulously considered using various techniques, including titration, EDX, XRD, FTIR, TGA, and FE-SEM. It was observed that the degree of polymerization, yield, and crystallinity of OCW was influenced by the NaOH concentration and exhibited variations in different directions. FTIR analysis indicated successful selective oxidation of the hydroxide groups of CW. XRD and FE-SEM results revealed thorough oxidation penetration throughout the waste cotton, disrupting its consistency and length while preserving its crystal structure. This paper presents a straightforward green approach for fabricating OCW with high crystallinity and specific surface area. The resulting OCW holds promise for applications such as adsorption and photodegradation of organic pollutants in refinery wastewater (RWW), contributing to environmental sustainability.
