Sorption of oxytetracycline to iron oxides and iron oxide-rich soils.

摘要: The sorption interactions of oxytetracycline with goethite, hematite, and two iron oxide-rich soils were investigated using batch experiments. Oxytetracycline coefficients for goethite hematite increased pH to maximum values at ∼8. edge shape desorption treatments consistent a surface complexation mechanism could be described by the interaction divalent anion species oxide surface. Georgeville Orangeburg Ultisol decreased pH. Chemical digestion used deduce that soil occurred coatings on clay quartz grains. These results indicate models must consider oxytetracycline, other similar ionogenic compounds, components in addition clays organic matter when predicting whole soils.
