Adsorption of levofloxacin onto goethite: Effects of pH, calcium and phosphate

- We investigate adsorption of levofloxacin (LEV) onto goethite.
- The maximum amount of LEV onto goethite is observed at pH 6.
- Less LEV is adsorbed in the presence of Ca2+ due to the complexation with Ca2+.
- Phosphate decreases LEV adsorption strongly.
