Opis (eng)

Abstract: Adsorption of the antibiotic ciprofloxacin (CIP) from an aqueous solution by calciumrich clinoptilolite (CLI) was investigated. Obtained results showed that natural CLI possesses a high adsorption efficiency in the removal of CIP at 283, 288 and 293 K and at pH= 5. Adsorption kinetics studied for the initial CIP concentrations of 15–75 mg dm–3 follow Lagergren’s pseudo-second order equation and the adsorption is best represented by the Langmuir model. The adsorption mechanism involves strong electrostatic interactions between aluminosilicate lattice of CLI and the cationic form of CIP accompanied by an ion-exchange reaction. The CIP saturated CLI was successfully regenerated by a cold atmospheric pressure plasma treatment.
