Retention of the Antibiotic Cefuroxime onto Agricultural and Forest Soils

Antibiotics in wastewater, sewage sludge, manures, and slurries constitute a risk for the environment when spread on soils. This work studies adsorption desorption of antibiotic cefuroxime (CFX) 23 agricultural forest soils, using batch-type experiments. Our results show that values were between 40.75 99.57% while range was lower (from 74.57 to 93.46%) Among Freundlich, Langmuir, Linear models, Freundlich equation shows best fit results. In addition, soils with higher pH are ones present highest adsorption. Further confirmation influence is given by fact Freundlich’s KF parameter model Kd positive correlation exchangeable Ca Mg values, which known affect charges soil colloids formation cationic bridges adsorbents adsorbate. n significant organic matter content, related high taking place despite their < 5. Regarding desorption, most cases, it than 1%, indicates CFX adsorbed rather irreversible way onto these Overall, can be considered relevant regarding potential impact environmental quality public health.
