Both these methods are less cumbersome and sensitive fluorometric methods which are developed from less expensive materials. CuMOF offered the oxidation route of thiamine to thiochrome, which is a fluorescence compound; through which thiamine was detected conveniently by measuring thiochrome. On the other hand, rhodamine B bound graphene oxide–RhGO, released rhodamine B upon interaction with the thiamine through the competitive binding against the rhodamine B located on the graphene oxide, which allowed us to develop a facile sensor for thiamine in DMF. Moreover, the sensitivity of the sensor was improved through the encapsulation effect with cucurbit[7]uril (CB[7]). The limits of detection (LOD) for CuMOF and RhGO with CB[7] were determined to be 48.39 × 10<sup>–8</sup> M and 68.33 × 10<sup>–8</sup> M, respectively. The sensing ability of RhGO was effectively utilized in commercially available thiamine drugs, and its performance was evaluated against other hydrochloride drugs such as metformin, ciprofloxacin, and cetirizine demonstrating its suitability for real-time sample analysis. This approach provides a practical solution for both analytical and pharmaceutical laboratories. Overall, two different detection methods for thiamine have been developed with good selectivity and sensitivity.</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":"21 12","pages":"2983 - 2991"},"PeriodicalIF":2.2,"publicationDate":"2024-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142645623","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}

A simple and novel modified method for the determination of sulfate was developed by using UV–Vis spectroscopy. The procedure involved the precipitation of sulfate as barium sulfate and the removal of interference under controlled conditions, using different reagents such as acid, glycerol and ethanol.
