Abstract The addition of biochar (BC) during composting significantly influences the concentration and chemical structure dissolved organic matters (DOM), thereby affecting its binding properties with heavy metals (HMs). This study examines co-composting chicken manure varying BC dosages, specifically 0 wt% (CK), 1 (T1), 2 (T2), comparatively analyzes characteristics between compost-derived DOM copper ions (Cu(II)). EEM-PARAFAC analysis identified three primary components in DOM: fulvic acid-like (C1), humic (C2), protein-like (C3) components, each exhibiting distinct Cu(II) properties. complexation constants (logK) for these increased addition, whereas fraction bound sites (f values) decreased, indicating that BC-amended compost forms more stable DOM-Cu(II) complexes but fewer available sites. 2D-COS synchronous fluorescence spectra revealed fulvic-like peaks were sensitive to variations across all types, while humic-like substances exhibited a stronger preference binding. HPSEC results showed broad molecular weight (MW) distributions (100–300,000 Da) DOM, significant decrease medium MW regions (1000-30,000 as increased, suggesting fractions are particularly binding, leading higher weight-averaged values concentrations. provides new insights into how can influence behavior HMs, highlighting potential enhancing HMs immobilization compost-amended soils.

Nanoscale zerovalent iron (nZVI) is a promising remediation agent for the removal of heavy-metal wastewater. However, nZVI tends to agglomerate and be oxidatively deactivated during reaction, which limits its application. To address problem, this study develops novel modification method regulate reaction interface by introducing fulvic acid (FA), naturally occurring environmental component, synthesis nZVI. FA disrupts circumferential-stress equilibrium nZVI, enhances Kirkendall effect, establishes mass-transfer channels, facilitating outward transfer reducible Fe(II) electrons inward transport surface-adsorbed Cr(VI). The Cr(VI) further enhanced coupling FA-nZVI with Shewanella oneidensis MR-1, reduces Fe(III) hydroxides at interface, thereby preventing accumulation passivation layer that blocks channels. synergistic action channels MR-1 rate 4.7 times, ensuring more than 60% under extreme conditions. By exploring new functions as an organic carbon provides fresh perspective on utilization in ecosystems. Leveraging factors microstructural modulation efficient environmentally friendly approach pollution.
