Abstract

PURPOSE: To measure simply, in short time, with good reproducibility, the COD of water like as sea water containing a large amount of chlorine ion by processing as follows; first, thermal decomposition is applied with alkaline KMnO4; then a specified mixed acid solution is added for acidifying; thereupon the residual KMnO4 is measured by coulomb titration.
