Optimum grafting condition was established by varying the Fenton’s reagent composition, grafting time, temperature and biomass mass. About 30 % grafting yield was attained at a 1:200 [Fe<sup>2+</sup>]/[H<sub>2</sub>O<sub>2</sub>] Fenton’s reagent composition, 60℃, 60 min and 1 g biomass mass. Characterization results indicated a successful incorporation of carbonyl group (C<img>O), from the carboxyl group of methacrylic acid, on the surface of the biomass material.

The negative ΔGº values, obtained at 303 – 333 K for the sorption of MB and MG, indicated feasibility and spontaneity, while those of ΔHº and ΔSº were indication of exothermicity and a process occurring with reduction in randomness at the dye/copolymer interface. Aggregation of the outcome of the various tests portrayed the copolymer as an adsorbent of high physicochemical qualities with good dye adsorbing efficiency.

Naphthalene is one of the most available PAH, which has several negative impacts on living health. To eliminate naphthalene from wastewater, some physicochemical approaches are being taken in which adsorption is the most established one. In our present study, a novel membrane-like composite was prepared with PVA (Poly Vinyl Alcohol) and Silica nanoparticles which were modified by incorporating activated banana biochar to increase its efficiency. Characterizations like FT-IR, SEM, and EDX were performed to depict various characteristic features of the composite. The removal of naphthalene due to the adsorption process was studied experimentally by a batch study in different varying parametric conditions like different adsorbent dosages, contact time, pollutant concentration, temperature, pH, and agitation speed. From the results, the highest removal percentage was observed as 99.549 % with conditions like an adsorbent dose of 2 g/L, 160 rpm agitation speed, 20 mg/L initial naphthalene concentration, and 303 K temperature after 2 hrs. Mathematical modelling was done to evaluate the adsorption isotherm with the help of Langmuir and Freundlich models. Low cost, biodegradability, availability, and high removal efficiency have made the composite an effective adsorbent for wastewater treatment.</div></div>","PeriodicalId":100486,"journal":{"name":"Environmental Surfaces and Interfaces","volume":"3 ","pages":"Pages 55-64"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143182390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
