This paper describes a mechanochemical approach to the synthesis of novel fluorinated Schiff bases via\u00a0ball milling, which provides a fast, high-yield, and green alternative to conventional reflux methods. The synthesized fluorinated Schiff bases are evaluated for their adsorption capacity and efficiency in mercury removal and compared to assess their performance, demonstrating that ball milling produced compounds with comparable physical attributes to those produced via traditional solvent-based procedures. However, ball milling considerably shortened reaction time, with some reactions taking less than 5 min, and enhanced yields, reaching up to 92%, which is significantly higher than that achieved by conventional methods. The molecular structure of the synthesised Schiff bases is validated using analytical and spectroscopic techniques, including <jats:sup>1<\/jats:sup>H, <jats:sup>13<\/jats:sup>C NMR and mass spectroscopy, with chemical shifts confirming the\u00a0expected structures. Furthermore, the thermal stability of the synthesized Schiff bases is validated up to around 250\u00a0\u00b0C, demonstrating their robustness and suitability for various applications. Given their well-established\u00a0chelating properties, the selected Schiff bases (<jats:bold>M6-M9<\/jats:bold>) are studied for mercury adsorption. Structural variations, such as hydroxyl and carbonyl functionalities, are anticipated to enhance mercury binding, making these compounds potential candidates for environmental remediation. Notably, this research presents the first investigation of these specific fluorinated Schiff bases for mercury chelation,\u00a0demonstrating notable adsorption for mercury and highlighting their potential in heavy metal remediation.<\/jats:p>\n          <jats:p>\n            <jats:bold>Graphical Abstract<\/jats:bold>\n          <\/jats:p>","DOI":"10.1186\/s13065-025-01552-9","type":"journal-article","created":{"date-parts":[[2025,7,4]],"date-time":"2025-07-04T08:11:31Z","timestamp":1751616691000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Efficient mechanochemical synthesis of new fluorinated Schiff bases: a solvent-free, alternative to conventional method with mercury adsorption properties"],"prefix":"10.1186","volume":"19","author":[{"given":"Mirza T.","family":"Baig","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariam T.","family":"Sayed","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reem","family":"Aledamat","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sumyah","family":"Hassan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alaa","family":"AlReyashi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naheed","family":"Sidiq","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siham Y.","family":"Al-Qaradawi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamed F.","family":"Mady","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2025,7,4]]},"reference":[{"issue":"2","key":"1552_CR1","doi-asserted-by":"publisher","first-page":"725","DOI":"10.1007\/s12011-023-03703-2","volume":"202","author":"SS Habib","year":"2024","unstructured":"Habib SS, Naz S, Fazio F, Cravana C, Ullah M, Rind KH, Attaullah S, Filiciotto F, Khayyam K.
