Adsorption and Desorption of three Fluoroquinolones Antibiotics on Tropical Soils

摘要：

　　On the basis of the OECD Guideline 106,Batch equilibrium experiments were used to reveal three fluoroquinolones antibiotics adsorption/desorption on tropical soils.Results showed that the experimental data were best described by the Freundlich and Langmuir model.Different sorption behaviors of three fluoroquinolones antibiotics were observed in tropical soils,with the lgKf values varying greatly from 2.986(Norfloxacin),2.850(Ciprofloxacin) and 3.086(Ofloxacin).Adsorption isotherms resembled the L-type curves.The dominant mechanism of three fluoroquinolones antibiotics adsorption was physical adsorption on tropical soils.In addition,desorption rate of three fluoroquinolones antibiotics were higher than adsorption rate on tropical soils,and the apparent sorption-desorption hysteresis was also observed.
