Method for Determining the Oxygen Requirement of an Aqueous Solution for a Purification Process

摘要

Method of determining the oxygen demand, TOD or COD, of an aqueous solution, in particular of waste water, for a clarification process, wherein a sample of the aqueous solution is decomposed by combustion, such that the combustion is carried out without the presence of a catalyst, at a temperature above 1150° C., in particular at 1200° C.
