Macroscopic and molecular approaches of enrofloxacin retention in soils in presence of Cu(II)

- Sorption process was evidenced using various pH and ionic strength conditions combined with kinetics.
- Copper enhances enrofloxacin retention onto soils.
- EXAFS spectra evidence the formation of a ternary complex.
- Formation of a ternary complex leads to an increase of the adsorbed flumequine amount.
