Spectroscopic Investigation of Ciprofloxacin Speciation at the Goethite−Water Interface

We investigated ciprofloxacin (a fluoroquinolone antibiotic) speciation as a function of pH in aqueous solution and in the presence of dissolved ferric ions and goethite using ATR-FTIR and UV−vis spectroscopy. The presence of dissolved and surface bound ferric species induced the deprotonation of th...
