| Abstract | As one of the widely used antibiotics in the world, the environmental behavior of tylosin (TYL) received more and more attentions. In order to assess its environmental and ecological risks accurately, it is necessary to understand the sorption properties of TYL on the soils/sediments. The sorption of TYL on goethite at different conditions were investigated through a series of batch experiments and the sorption data of TYL were fitted by Freundlich model and dual mode sorption model. It was obvious that sorption was strongly dependent on pH and ionic strength. Sorption capacity of TYL increased as the pH increased and ionic strength decreased. The pH and ionic strength-dependences might be related with the specific complexation between cationic/neutral TYL and goethite. Spectroscopic evidence indicated that tricarbonylamide and hydroxyl functional groups of TYL might be accounted for the sorption on mineral surface. The experimental data of TYL sorption could be fitted by surface complexation model (FITEQL), indicating that ≡FeOH with TYL interaction could be reasonably represented as a complex formation of a monoacid with discrete sites on goethite. It should be noticed that the heterogeneous of sorption affinity of TYL on goethite at various environment to assess its environment risk |
