Abstract (en)
[origin: DE10240410B3] Determining the oxygen requirement, total oxygen requirement or chemical oxygen requirement of an aqueous solution, especially effluent, in a clarifying process comprises digesting a sample of the aqueous solution by burning at above 1150degreesC in a vertical reaction chamber without using a catalyst, and removing salts obtained in the sample at the lower end of the reaction chamber.
