文摘
- •
The characteristics of DOM extracted from four particle-size sediments were compared.
- •
Particle size obviously influenced the quality and quantity of extracted DOM.
- •
Protein-like material dominated in DOM and processed a stronger complex capacity with As/Sb.
- •
The binding capacity of DOM with As/Sb decreased with the increasing particle size.
- •
A positive correlation between complexation capacity and acidic functional group content.
