Removal of antibiotics from contaminated waters using natural zeolite
Abstract
dc:description.abstractThe occurrence of residual antibiotics in the environment has been a worldwide issue, and there is a need to develop methods for antibiotics removal from contaminated water. In this thesis work, the sorption of four antibiotics, namely chlortetracycline (CTC), oxytetracycline (OTC), ofloxacin (OFL), and enrofloxacin (ENR), on natural zeolite was investigated. The impact of pH and natural organic matter (NOM) on the sorption process was examined, and the maximum sorption capacity was calculated using the Langmuir-Freundlich sorption model. The results showed that at a neutral pH the maximum sorption capacity for the antibiotics was up to 8 mg/g. The sorption capacity increased as the solution pH decreased. The presence of NOM reduced the sorption of OTC but enhanced the sorption of the remaining antibiotics.
