Nanostructured MgO-enhanced catalytic ozonation of petrochemical wastewater

Petrochemical wastewater, which is a complex solution of various chemicals, can cause severe environmental problems after being disposed to environment. Here, we investigate the removal of petrochemical contaminants at different periods and pH levels using three distinct processes: conventional ozon...
