Oxidation of cyanide in effluents by Caro's Acid

► The kinetics of Caro's Acid oxidation of CN have been quantified. ► We confirmed that Caro's Acid oxidation of cyanide to cyanate is very fast. ► Ten minutes for [CN] reduction from 400 mg/L to 1 mg/L in a batch reaction. ► Fast oxidation conditions do not require addition of catalysts.
