Ciprofloxacin and Trimethoprim Adsorption/Desorption in Agricultural Soils.

ABSTRACT: The current research focuses on the adsorption/desorption characteristics of the antibiotics ciprofloxacin (CIP) and trimethoprim (TRI) taking place in 17 agricultural soils, which are studied by means of batch-type experiments. The results show that adsorption was higher for CIP, with Freundlich K_F values ranging between 1150 and 5086 Lⁿ µmol^1-n kg^-1, while they were between 29 and 110 Lⁿ µmol^1-n kg^-1 in the case of TRI. Other parameters, such as the Langmuir maximum adsorption capacity (q_m(ads)), as well as the K_d parameter in the linear model and also the adsorption percentages, follow the same trend as K_F. Desorption was lower for CIP (with K_F(des) values in the rang
