In solution applications, other destruction processes, such as the hydrogen peroxide process, are preferred to the Caro's acid process. The theoretical usage of H2SO in the process is 4.39 grams H2SO5 per gram of cyanide oxidized, but in practice 5.0 to 15.0 grams H2SO5 per gram of cyanide oxidized is required.
