We applied FT-ICR-MS, XPS, and other techniques to investigate the interfacial behavior of CDOM from coal, charcoal, pinewood, and maize straw on kaolinite and montmorillonite. Two distinct mechanisms were identified: ligand exchange on kaolinite (increasing binding energies by 1.2 \u223c 1.7 eV) and Ca2+\/Mg2+-mediated cation bridging on montmorillonite (decreasing binding energies by 0.3 \u223c 1.8 eV). Maize straw-CDOM and charcoal-CDOM exhibited the highest adsorption on both clays, while pinewood-CDOM showed mineral-selective retention (montmorillonite only) and coal-CDOM showed negligible adsorption. Coal-CDOM (\u2212SO3H-rich) with negligible adsorption was due to electrostatic repulsion and hydration steric hindrance. Pinewood-CDOM (phenolic) was retained only on montmorillonite via cation bridging, as its phenolic groups cannot undergo ligand exchange with kaolinite. Charcoal-CDOM (\u2212NH2-rich) was retained on both clays primarily through electrostatic attraction of \u2013NH3+, with additional contributions from Ca2+\/Mg2+-mediated cation bridging and cation\u2013\u03c0 interactions on montmorillonite. Maize straw-CDOM (mixed \u2013COOH, \u2013NH2, \u2013SO3H) was retained through synergistic ligand exchange, cation bridging, and electrostatic\/H-bonding. Concentration-dependent fractionation shifted from H-bonding\/electrostatic attraction (small polar molecules) to hydrophobic\/cation\u2013\u03c0 interactions (large aromatic molecules) with increasing concentration. This framework provides mechanistic context for pyrogenic carbon sequestration and contaminant mobility in clay-rich environmental matrices.<\/jats:p>","DOI":"10.1021\/acs.est.6c07762","type":"journal-article","created":{"date-parts":[[2026,9,30]],"date-time":"2026-09-30T04:02:06Z","timestamp":1790740926000},"page":"28741-28755","source":"Crossref","is-referenced-by-count":0,"title":["Molecular Fingerprint-Dependent\nRetention and Fractionation\nof Combustion-Derived Dissolved Organic Matter on Kaolinite and Montmorillonite"],"prefix":"10.1021","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6667-2403","authenticated-orcid":true,"given":"Weifeng","family":"Chen","sequence":"first","affiliation":[{"name":"Fujian Normal University , , , ,","place":["Fuzhou, Fujian, China, 350007"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yixin","family":"Xu","sequence":"additional","affiliation":[{"name":"Fujian Normal University , , , ,","place":["Fuzhou, Fujian, China, 350007"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Wang","sequence":"additional","affiliation":[{"name":"Jiangsu University , , , ,","place":["Zhenjiang, Jiangsu, China, 212013"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0244-4839","authenticated-orcid":true,"given":"Youtao","family":"Si","sequence":"additional","affiliation":[{"name":"Fujian Normal University , , , ,","place":["Fuzhou, Fujian, China, 350007"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huiying","family":"Zhang","sequence":"additional","affiliation":[{"name":"Fujian Normal University , , , ,","place":["Fuzhou, Fujian, China, 350007"]},{"name":"Tsinghua University , , ,","place":["Beijing, China, 100084"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4284-8096","authenticated-orcid":true,"given":"Hualong","family":"Hong","sequence":"additional","affiliation":[{"name":"Xiamen University , , , ,","place":["Xiamen, Fujian, China, 361102"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdallah","family":"Abdelfattahe","sequence":"additional","affiliation":[{"name":"Tanta University , , ,","place":["Tanta, Egypt, 31511"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-4459-9050","authenticated-orcid":true,"given":"Hui","family":"Jia","sequence":"additional","affiliation":[{"name":"Fujian Normal University , , , ,","place":["Fuzhou, Fujian, China, 350007"]},{"name":"Jiangsu University , , , ,","place":["Zhenjiang, Jiangsu, China, 212013"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,29]]},"reference":[{"key":"2026101310165467900_cit1","doi-asserted-by":"publisher","first-page":"4335","DOI":"10.1021\/cr5006167","article-title":"Chemistry of atmospheric brown carbon","volume":"115","author":"Laskin","year":"2015","journal-title":"Chem.
