摘要： On the basis of OECD Guideline 106, batch sorption methods were employed to reveal the effect of Ca(2+) ion strength and different cations (0.01 mol/L solution of NaCl, NH(4)Cl, MgCl(2) and AlCl(3)) on oxytetracycline (OTC) sorption-desorption process in four tested tropical soils collected from Haikou, Sanya, Chengmai, Qionghai city, Hainan province, China. Results showed that the Freundlich model (r>0.831) was the better isotherm than Langmuir model (r>0.698). The relationship between lgK(f) value of four tropical soils and the corresponding concentration of CaCl(2) showed a significant negative correlation (p < 0.05). In the test concentrations, as CaCl(2) concentrations of solution increased, K(d) values of OTC in four tropical soils demonstrated a down, then up and, finally, significant linear trend. The valley points were located in CaCl(2) concentration of 0.08 mg/L. Desorption parameters of OTC in four soils were similar to adsorption process, and the extent of hysteresis was different. The effects of pH of soils could not be ignored on the adsorption. When OTC coexisted with different exogenous cations, it presented larger adsorption capacity (lgK(f)) of tropical soils, which ranged from 1.885 to 3.722. As for the same cation medium, different tropical soils had different adsorption capacity (lgK(f)) of OTC. At the low pH, cationic and zwitter-ionic form of OTC was predominant in equilibrium solutions, so cation sorption, hydrogen bonding, electrostatic adsorption or dipole moment could be the main sorption mechanism. Results also indicated that different cations inevitably resulted in difference of OTC sorption.
