Enhanced Sorption of OTC on Clays via Complexation with Zn2+
Zn2+络合促进土霉素在粘土矿物表面的吸附

Oxytetracycline(OTC) and Zn~(2+) are both widely used as growth promoters in concentrated animal feeding operations,which are discharged into soil system by manure application.There is special environment significance to study the sorption and interaction of OTC with accompanied metal cations on clays to elucidate their environmental behaviors and to assess ecological risks.Much stronger sorption of OTC was observed on montmorillonite than that on kaolinite,which might be resulted from the larger cation exc...
