Regarding the measurement of COD, we have confirmed through an on-going COD reduction project in Finland that H2O2 is a positive interference for the dichromate COD test (CODCr), increasing the results. To compensate for this a separate titration for H2O2 was completed by one research partner and then subtracted from the CODCr results. The other partners are using the photoelectrochemical (peCOD) method. A green chemistry method with results in 15min. The peCOD does not suffer from the H2O2 interference and measures the correct COD value in one step.

we used hydrogen peroxide along with AOP with nano catalysts to treat wastewater and was wondering why results shows higher COD when using hydrogen peroxide comparing to results we are not using it. now I can understand the reason. thank you for your help
