[Bichromate oxidizability as a measure of the quantitative amount of organic impurities in regenerated water].

Experiments have been carried out to study permanganate and bichromate oxidation of chemicals that may contaminate reclained water, initial and intermediate products of reclamation. Permanganate oxidability can be used as a qualitative indicator of water contamination with readily oxidizable admixtures only. Bichromate oxidability can be employed as a quantitative indicator of the total content of organic admixtures, provided that oxidation is carried out in a certain way. For the water reclaimed from the atmospheric condensate the following correlation between bichromate oxidability and the concentration of admixtures has been established: 1 mg O2 consumed corresponds approximately to 0.66 mg of organic admixtures in water.
