Degradation of 2-Chlorophenol from Wastewater Using γ-Fe2O3 Nanoparticles

In this study, magnetic nanoparticles (γ-Fe2O3) were used for the degradation of 2-chlorophenol (CP) from wastewater. The size of these magnetic nanoparticles was measured using XRD and found to be about <50 nm. Experiments for the CP degradation by the γ-Fe2O3 nanoparticles from wastewater were carried out under ultrasound irradiation. Major influence factors on the degradation efficiency, such as, ultrasonic time, and initial pH value, were investigated. The results indicated that the γ-Fe2O3 nanoscale particles were very effective for the CP degradation. The degradation efficiency was 45% in 25 min under the ultrasonic irradiation. The effect of initial pH value showed that the degradation percent was improved by increasing the pH of solution.
