A similar uptake trend was found for both MOFs, with Basolite\u00ae F300 being the more effective given its higher porosity and greater surface area. Pseudo-second-order kinetic models were followed by MMA, DMAA, ASA, and As(V), suggesting a chemisorption mechanism with arsenic species diffusion into MOF pores as the controlling step. Equilibrium data for DMAA and ASA fit the Langmuir model whereas MMA adsorption fits the Redlich\u2013Peterson model. The uptake of MMA, DMAA, and ASA by both Fe-MOFs is mainly attributed to their coordination with Fe(III). Aromatic units in ASA enhance adsorption through \u041f-\u041f stacking interactions. The competition between all arsenic species for the sorption sites of the Fe-MOFs led to an uptake decrease of 10% for MMA and ASA and higher than 30% for DMAA and As(V) with respect to the individual uptakes. The Fe-MOFs can be reused for four cycles by washing with acidic methanol. Basolite\u00ae F300 and synthetic nano-{Fe-BTC} effectively removed organic and inorganic arsenic species, exhibiting rapid adsorption, selective uptake, stability, and easy regeneration.<\/jats:p>","DOI":"10.3390\/molecules30214198","type":"journal-article","created":{"date-parts":[[2025,10,29]],"date-time":"2025-10-29T02:23:28Z","timestamp":1761704608000},"page":"4198","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Iron-Based Metal\u2013Organic Frameworks for the Removal of Different Organic and Inorganic Arsenic Species from Water: Kinetic and Adsorption Studies"],"prefix":"10.3390","volume":"30","author":[{"given":"Afef","family":"Azri","sequence":"first","affiliation":[{"name":"Department de Qu\u00edmica, Facultat de Ci\u00e8ncies, Universitat de Girona, C\/M\u1d43 Aur\u00e8lia Capmany, 69, 17003 Girona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7057-0821","authenticated-orcid":false,"given":"Khaled","family":"Walha","sequence":"additional","affiliation":[{"name":"Laboratory of Material Sciences and Environment, Faculty of Sciences, University of Sfax, Sfax 3029, Tunisia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5947-4126","authenticated-orcid":false,"given":"Claudia","family":"Font\u00e0s","sequence":"additional","affiliation":[{"name":"Department de Qu\u00edmica, Facultat de Ci\u00e8ncies, Universitat de Girona, C\/M\u1d43 Aur\u00e8lia Capmany, 69, 17003 Girona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9-Elias","family":"Conde-Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Departamento de Qu\u00edmica, Unidad Departamental de Qu\u00edmica Anal\u00edtica, Facultad de Ciencias, Universidad de La Laguna, Avda.
