title: Study of the interaction of trimethoprim-montmorillonite by infrared spectroscopy.
abstract: The interaction of trimethoprim with montmorillonite has been studied under different pH conditions and ionic strengths. Infrared spectra indicate that the interaction is favoured by cation-exchange mechanism at low pH, and by physical adsorption at high pH. This is also supported by adsorption isotherms and the desorption process which is reversible at low acidity.
