The current study for the extraction and enrichment of paracetamol is based on the use of rhamnolipid biosurfactants in emulsion-based liquid-phase microextraction. The separation mechanism of paracetamol is based on the emulsion formation of the biosurfactant-rich phase. First, a bioemulsion solution (colloidal phase) was formed and then the analyte was isolated onto the non-aqueous phase. The second step consists of backextraction of the analyte into an aqueous acceptor phase. Finally, the aqueous acceptor phase was withdrawn using a microsyringe and injected into a liquid chromatography instrument for quantitative analysis. The ability of rhamnolipid biosurfactants to form a stable colloidal phase with regions of different polarities can lead to extraction analyte using van der Waals interactions. Considering the biodegradability of biosurfactants and the removal of chemical surfactants in the sample preparation process, the present method is environmentally friendly. Several influencer factors on extraction efficiency including the amount of rhamnolipid biosurfactant, methanol volume, pH, extraction time, ionic strength, and centrifugation time were investigated and optimized.

This results in the presence of dangerous substances and toxic pollutants, which raises significant worldwide concerns. Considering the increasing environmental issues, it is essential to develop innovative and durable strategies for mitigating pollution. Graphitic carbon nitride (GCN or g-C<sub>3</sub>N<sub>4</sub>), a metal-free photocatalyst, has demonstrated potential as a material for environmental remediation. This is attributed to its distinctive physicochemical properties, electronic band structure, non-toxic nature, abundance of raw materials, simple preparation methods, and ability to utilize solar energy. However, the limited ability of pure g-C<sub>3</sub>N<sub>4</sub> to undergo reduction and oxidation, as well as its high rate of recombination of photogenerated electron–hole pairs, restricts its applicability in photocatalysis. These issues have been overcome through the implementation of several modifications, including elemental doping, heterojunction building, morphological adjustments, and defect engineering. This review article provides a thorough overview of photocatalysts based on g-C<sub>3</sub>N<sub>4</sub> that are utilized for the elimination of various types of pollutants, including both organic and inorganic contaminants.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":676,"journal":{"name":"Journal of the Iranian Chemical Society","volume":"22 8","pages":"1659 - 1682"},"PeriodicalIF":2.3,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145062138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
