Effects of Temperature on the Adsorption and Desorption of Tetracycline in Soils

Abstract:

Batch experiments of OECD Guide were conducted to the adsorption and desorption of tetracycline in soils. The adsorption and desorption isotherms of tetracycline in cinnamon soil and red soil were expressed well by the Freundlich equation at 20, 25 and 35°C. According to lg K_f and 1/n values of fitting parameters, tetracycline was strongly adsorbed by two soils with adsorption capacity (lg K_f) values from 3.06 to 3.59. Temperature from 20 to 30°C had little effects on the tetracycline adsorption in two soils. Thermodynamic parameters depict the exothermic nature of adsorption, and the process was favorable and spontaneous. Hysteresis effect was observed. The maximum adsorption capacity and hysteresis index of tetracycline were found at 20°C for cinnamon soil and 30°C for red soil, so there was little risk of tetracycline remobilization with temperature lower than 25°C in cinnamon soil or higher than 25°C in red soil.
