In this work an electrochemical sensor was developed using graphene nanoplatelets (GNP) decorated zirconium and nitrogen doped graphitic carbon nitride (Zr-N-GCN) nanocomposite for detection of As<sup>3+</sup> ions in tap water and juice samples.

Developing efficient methods for their distinguishment is crucial for pharmaceutical quality control. Here, we presented a novel approach using a CTT (Chlorite-Tetramethylammonium Hydroxide-Tetrathionate) clock reaction system for kinetic chiral enantiomer recognition. DOPA enantiomers were selected for this purpose, in which L-DOPA is therapeutic efficacy in treating Parkinson's disease by precursoring dopamine while D-DOPA lacks such a function. By introducing equal amounts of L-DOPA and D-DOPA into the CTT clock system, we observed a more prolonged induction period for L-DOPA compared to D-DOPA, enabling their quick differentiation. Moreover, a linear relationship between the induction period and the concentration (1.190 × 10<sup>−6</sup> mol/L to 4.5238 × 10<sup>−6</sup> mol/L) of L-DOPA or D-DOPA allowed quantitative detection of L-DOPA or D-DOPA samples. This method could also be applied to analyze varying concentration ratios of L-DOPA and D-DOPA mixtures at a fixed total concentration. Study on mechanism indicates that both L-DOPA and D-DOPA react with ClO<sub>2</sub>· radical to finally generate DHICA through oxidation, with their kinetic disparities evident during this process. These kinetic disparities between L-DOPA and D-DOPA oxidation arises from stereospecific hydrogen-bonding interactions in the cyclodopa intermediate. The weaker hydrogen bond in L-DOPA-derived cyclodopa likely facilitates its cleavage during oxidation, thereby accounting for the faster reaction kinetics observed in the clock system compared to D-DOPA. This makes L-DOPA exhibit more fast consumption of chlorine dioxide than D-DOPA, and resulting larger the extension in the induction period with L-DOPA than that with D-DOPA. Such a method coupling CCT clock demonstrates its versatility and potential for broader applications in chiral drug analysis.</div></div>","PeriodicalId":355,"journal":{"name":"Journal of Electroanalytical Chemistry","volume":"996 ","pages":"Article 119432"},"PeriodicalIF":4.1,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144917481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
