Propanol is also a small organic molecule; it reacts with potassium dichromate during COD measurement, which definitely affects the determination of COD. Of course, B also constitutes a component contributing to COD.

It will have an impact; the higher the concentration of C, the higher the COD. Such issues can be posted for discussion in the water treatment section of the Safety and Environment section.
