The optimal nitric acid concentration for modification was 3 mol/L (BAC-N3), which had more acid functional group contents than unmodified. The chemical oxygen demand (COD) removal rate was to reach 77.05% when 4 g BAC-N3 was added into 50 mL coking wastewater in 120 min with a shaking speed of 100 rpm at 25°C.

Moreover, acid precipitation had efficaciously eliminated the COD from the laundry wastewater and paper mill wastewater [4, 5]. Additionally, either CO 2 or mineral acids were introduced to reduce the pH. COD removal by adsorption via GAC offers a mature, simple, and cost-effective process with regard to the process of advanced oxidation.
