Consequently, developing precise methods for detecting TC residues in water is crucial. Herein, we present a facile method for TC fluorescence sensing utilizing Zr-MOF (MOF-808). MOF-808 exhibits exceptional luminescence properties, maintaining stability in water for up to 10 days and across a broad pH range of 3–12. Detection results indicated that MOF-808 served as an efficient luminescent probe for TC detection in aqueous solutions, demonstrating high sensitivity with a low detection limit of 7.26 nM and a rapid response time within 10 s. Notably, MOF-808 displayed high selectivity for TC over other common anions and metal cations in water. The sensing mechanism was elucidated through comprehensive analysis, revealing that the internal filtration effect (IFE) induced the fluorescence quenching of MOF-808. The interaction between TC and MOF-808 was crucial for the preconcentration of TC, leading to a swift fluorescent response with high quenching efficiency. The practical applicability of MOF-808 was further confirmed by its successful detection of TC in real environmental water samples.</div></div>","PeriodicalId":13609,"journal":{"name":"Inorganic Chemistry Communications","volume":"178 ","pages":"Article 114548"},"PeriodicalIF":4.4,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143864345","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}

Firstly, the MPR was characterized by different techniques, namely Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM). Nitrogen sorption analysis shows that the BET specific surface area and pore volume of the sample are 18 m².g⁻¹ and 0.11 cm³.g⁻¹, respectively. The effects of operating parameters on the fixed-bed column performance are examined, including initial AOG concentration (10–39 mg.L^-1), flow rate (5–30 mL.min⁻¹), and bed height (3.8–15 cm). Experimental data showed that the adsorption column’s maximum capacity varied between 1.44 and 3.00 mg.g⁻¹, the rather than its removal efficiency was found to be varied from 20.01 to 38.8 %. Additionally, residence time distribution (RTD) analysis highlighted the influence of flow rate on axial dispersion and flow uniformity, confirming that higher flow rates reduce residence time heterogeneity and shift the system toward more plug-flow-like behavior. Dynamic adsorption models, including the Thomas, Bohart-Adams, Yoon-Nelson, Bed Depth Service Time (BDST), and their corresponding modified logarithmic models were applied to predict the asymmetric breakthrough curves obtained from the fixed-bed column adsorption tests. According to the results, MPR fixed-bed column for AOG removal was well fitting logarithmic models. It can be concluded that the low specific surface area, heterogeneous particle size distribution, weak intraparticle, and surface diffusion of MPR were responsible on the asymmetrical curves. In addition, the bed regeneration was conducted at room temperature using acetic acid (0.1 N), and the results showed that the MPR could be efficiently reused for four consecutive cycles. Finally, the natural Moroccan phosphate rock could be employed as a potential adsorbent to remove azo dyes from wastewater.</div></div>","PeriodicalId":13609,"journal":{"name":"Inorganic Chemistry Communications","volume":"178 ","pages":"Article 114544"},"PeriodicalIF":4.4,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143860110","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}
