As(III)-to-As(V) Oxidation in Copper Smelter Wastewater by In Situ-Generated Ozone

As(III) is the most common arsenic species in copper smelter wastewater but is difficult to remove, and an oxidation to As(V) is desirable. The oxidation of As(III) to As(V) in copper smelter wastewater was studied using in situ-generated ozone, which has
