Method for the oxidation of values present in low valence stages and dissolved in liquids

摘要

Method for the oxidation of values present in low valence stages in liquids and of compounds which stabilize these low valence stages if they are present. Dinitrogen tetroxide (N2O4) in liquid form is added to the value solution as an oxidation agent. The oxidation reactions which subsequently take place are conducted as substantially liquid-liquid reactions.
