Abstract
Petroleum refineries release wastewater rich in organic pollutants and difficult to treat.
Study presents the treatment of petroleum refinery wastewater using nanoscale zero valent iron (NZVI) in the presence of ultrasonication.
NZVI characteristics were analyzed using SEM and XRD. Results indicate that a dosage of 0.15 g/l and an initial pH are optimum for the effective degradation of effluents. The degradation data were found to follow first order kinetics. Results suggest that using NZVI in combination with ultrasonication is an efficient method for the treatment of petroleum refinery wastewater.
