Abstract

Abstract

En 中文
• Mineral surface chemistry and DOM composition jointly control their interactions. • C=C/C=O, C-O-C and C-O groups consistently dominate at mineral-organic interfaces. • Adsorption capacity, sequence and preferential selection of OM vary among minerals. • Reactive group abundances in DOM govern their adsorption capacity onto minerals. • MAOM form via mineral-organic and organic-organic interactions.
