Field-emission scanning electron microscopy revealed semi-circular nanoparticles with an average grain size of 70 nm, providing insights into surface morphology, shape, and particle distribution. Porosity studies using N₂ sorption confirmed the mesoporous nature of the adsorbent, with a specific surface area of 14.22 m²/g, pore volume of 0.050 m³/g, and an average pore size of 3.067 nm. The adsorption performance was evaluated under varying conditions, including pH, adsorbent dosage, contact time, and antibiotic concentration. Optimal removal efficiency was achieved at pH 6, 0.02 g adsorbent, 50 min of contact time, and an initial antibiotic concentration of 15 mg/L. Under these conditions, the maximum removal efficiencies for tetracycline and oxytetracycline were 97.16% and 91.73%, respectively. Kinetic studies indicated that the adsorption process followed a pseudo-second-order kinetic model and aligned with the Langmuir isotherm.

The progress of the reaction is studied by measuring the reduction in absorbance, employing the pseudo-first-order condition as an indicator of [SLS], [Ag(I)], [D-Sorbitol], ionic strength, [Mn(VII)], and [H⁺]. The reaction exhibits fractional-first-order dependence on [H⁺], [D-Sorbitol], and [Ag(I)], and first-order reliance on [Mn(VII)] across the examined concentration spectrum. The kinetic examination showed that while Ag(I) and SLS individually accelerate the process, their combination is significantly more effective. Ag(I) markedly enhances the oxidation rate by a factor of 5.2. The kinetic profile demonstrated a 6.8-fold enhancement in the rate constant with an increase in surfactant concentration. The synergistic effect of Ag(I) and SLS micelles leads to an 11.3-fold increase in the oxidation rate of D-Sorbitol. The oxidation process is expedited by the electrostatic interaction between Mn(VII) and the negatively charged SLS micelle, facilitating the proximity of the oxidant to the substrate (D-Sorbitol), which is typically soluble in a micellar environment. A credible mechanistic framework that aligns with the kinetic results is being emphasized to elucidate the observable catalytic influence of the SLS micellar environment.</p></div>","PeriodicalId":666,"journal":{"name":"Journal of Solution Chemistry","volume":"55 7","pages":"1553 - 1567"},"PeriodicalIF":1.3,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148465892","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}

This study focuses on the solvent-mediated transformation of clopidogrel bisulfate from polymorphic form II to the more stable and pharmaceutically preferred form I to enhance its therapeutic efficacy. Comprehensive characterization using XRPD, FT-IR, UV–Vis, confirmed successful conversion and improved crystallinity. Notably, whereas prior electrochemical characterizations of clopidogrel polymorphs employed gold electrodes, this work is the first to utilize nickel‐foam electrodes. The Ni‐foam platform produced even more pronounced voltametric signals comparable in profile but with higher peak currents and lower over potentials than those recorded on gold underscoring its superior sensitivity for assessing polymorph‐specific redox behaviour. Theoretical studies employing DFT at the B3LYP/6–311 + G (d, p) level provided insights into molecular geometry, stability, and reactivity. Thermodynamic and FMO analyses further supported the electronic stability of form I. Hirshfeld surface analysis quantified key intermolecular contacts, revealing prominent hydrogen-bonding and π–π interactions that stabilize the crystal lattice. Molecular docking with the P2Y12 receptor (4NTJ) revealed a strong binding affinity (− 6.9 kJ·mol⁻¹), suggesting effective antiplatelet activity. Furthermore, this work establishes a cost-effective, solvent-mediated three-step strategy for controlling polymorphic transformation. By coupling redox analysis, stability profiling, charge transfer studies, and molecular docking, the approach ensures reproducible yield of the pharmaceutically superior form I.
