Abstract |
The study consisted of four samples which 74 participating laboratories were instructed to dilute to a specified volume and analyze by both the Standard Method for Chemical Oxygen Demand and by the Mercuric Sulfate modification. The results from this study indicate that the two procedures produce similar precision and accuracy when no interfering materials are present. When interferences due to high concentrations of chloride are present, the standard method will produce equal precision and accuracy only if the appropriate corrective techniques are applied. The Mercuric Sulfate modification is the method of choice for COD measurement since with less manipulation it effectively removes the interference due to chloride oxidation and is less time consuming.
