%X The sorption interactions of tetracycline antibiotics on loess soil surfaces under different pH and ionic strength conditions were investigated using batch sorption experiments. The results showed that tetracycline was adsorbed more strongly on loess surfaces than on loess-HA and the adsorption could be described by Freundlich isotherms. Adsorption of tetracycline on loess surfaces gradually decreased with the increase of natural cation concentrations in the solution, suggesting that cation exchange dominated the sorption processes. In addition, the sorption coefficients of tetracycline decreased as the pH increased from 4.0 to 9.0.
