Abstract
Investigations into oxidizing purification of subturpentine waters from sulphate cellulose production that contain hydrogen sulphide, methyl mercaptans, thiomethyl sulphides, dimethyl disulphides, turpentine, and methanol have been made. Hydrogen peroxide was chosen as an oxidizer. It has been found that hydrogen sulphide, dimethyl sulphides, dimethyl disulphides are subject to easy oxidation in the presence of H2O2. Methyl mercaptans and alternative organic compounds can be oxidized more effectively with the classic Fenton's reagent (H2O2, FeSO4, pH 2-3) and electrochemically with the use of H2O2.
