This increase has been caused by the discharge of untreated or incompletely treated pharmaceutical wastewater into aquatic environments. Metronidazole is a widely used antibiotic for the treatment of infections caused by anaerobic bacteria and protozoa. The present study investigated the efficacy of nano-pumice prepared from pumice mine waste as a low-cost adsorbent for metronidazole removal from aqueous environments. The effects of input variables, including pH, contact time, nano-pumice dose, and metronidazole concentration, were investigated. The experimental design was based on central point’s using the response surface method to study adsorption. After optimizing the input variables, isotherm and kinetic studies were conducted. The properties of the adsorbent were characterized through FESEM, XRD, BET, and FTIR analyses. The results indicated that the adsorption process followed a quadratic polynomial model, with F and p values of 990.936 and less than 0.0001, respectively. Additionally, the R² was 0.9989, and the Adj-R² was 0.9979. The optimal conditions for achieving a removal efficiency of 94.55% and maximum adsorption capacity of 15.313 mg/g were found to be pH = 3, contact time = 60 min, adsorbent dose = 1.5 g/L, and metronidazole concentration = 20 mg/L. Furthermore, the adsorption process aligned with the Langmuir isotherm and pseudo-first-order kinetics, as indicated by R² values of 0.9965 and 0.9859, respectively. Therefore, nano-pumice can be suggested as a natural and environmentally friendly adsorbent with significant potential for the adsorption of metronidazole and similar antibiotics from aqueous media.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"22 6","pages":"4091 - 4108"},"PeriodicalIF":3.0,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adsorption performance of the biochar samples is closely linked to the temperature at which pyrolysis was conducted. Significantly, biochar produced at higher temperatures demonstrates markedly enhanced adsorption capabilities compared to those from lower temperatures, with a surface area exceeding 250 m²/g.
