Dissolved organic matter (DOM) is widely present in soil environments and plays a crucial role controlling the morphology, environmental behavior, hazards of arsenic (As) soil. In Fe-rich red tea plantations, decomposition tree litter complicates DOM properties, leading to more uncertain interactions between DOM, Fe, As. This study focused on three plantations Huangshan City investigate contents As surface soils (Ferralsols) establish their correlations. Three-dimensional fluorescence spectroscopy PARAFAC analysis methods were used analyze components signatures. Additionally, process mechanism binding DOM-Fe with explored through laboratory experiments morphological transformation by DOM-Fe. The results showed that pH values ranged from 3.9 5.2, entire sample was strongly acidic. exhibited strong intrinsic properties low humification, containing types humic acid one intermediate protein component. DOC content did not have direct correlation Fe As, but interaction fractions significantly influenced content. Specifically, protein-like had pronounced effect maximum sorption rate 15.45%, this increased 49 75% participation Fe. configuration metal electron bridge, acts as cation, forming connecting channel negatively charged thus enhancing DOM’s capacity compounds bind pores functional groups. These findings provide deeper insights into influence behavior offer theoretical support for pollution
