Adsorption of Ciprofloxacin from solution on mesoporous silica MCM-48: Kinetic study

Abstract

Antibiotics in the environment can affect biotic processes, cause resistance to microorganisms, and have an effect on human health. Ciprofloxacin (CIP) is one of the antibiotics that is found as a pollutant in the aquatic environment. In this study, MCM-48 was used as a material to remove CIP from the solution. Adsorption of CIP on MCM-48 achieved the equilibrium at 80 minutes. The pseudo-second-order is the most suitable kinetics model to describe the adsorption process with a correlation coefficient value of 0.9997 and a rate constant k2 of 0.2684 g mg-1 min−1.
