Abstract

•Photocatalytic activity of Mg-doped ZnO was enhanced upon increased Mg2+ content.•Photodegradative process disinfected and improved the BOD5/COD ratio of wastewater.•Phytotoxicity tests showed that treated wastewater can be used in agriculture.•Mg-doped ZnO did not inhibit the proliferation of fibroblast cells.
