文摘
- •
Nanoparticle–EPS interaction was for the first time studied by EEM–PARAFAC technique.
- •
Three independent organic components were identified from all EEM spectra of EPS matrix.
- •
Binding potential was related to EPS fractions, organic components and nanoparticle types.
- •
The transportations of nano-CuO and nano-Fe3O4 would be controlled by LB– and TB–EPS, respectively.
- •
Toxicity of nanoparticles would be changed in eutrophic waters due to the presence of EPS.
