What is Dichromate Method for COD Analysis about?

The article discusses a study on the oxidizability of various organic substances using the dichromate method for determining chemical oxygen demand (COD). It categorizes organic compounds into three groups based on their oxidizability and highlights the limitations of the method, particularly in the presence of harder-to-oxidize substances. A modified procedure for reliable COD determination in pure waters is proposed, along with a standard mixture for verification.
