Please check this PDF attachment.

Sushanta Kumar Naik

The above attached pdf will not serve my purpose. I need the exact methodology as I stated in my question.

Manoj Kumar Tiwari

Dear sir

you can use the OC analysis by modified Walkley-Black titration for said water samples. Please check the attachment for the same

Dear Manoj Kumar Tiwari

The pdf did not describe about the DOC and that is suitable for soil and sediments.

Phanibhusan Ghosh

To me, it is very difficult to get exact value of DOC in waste water by titration method. By estimating BOD and COD, some idea about the level of DOC may be obtained by converting oxygen value into equivalent carbon value using the reaction between carbon and oxygen to form carbondioxide.
