Rezumat:

The objective of this work was a critical evaluation of analytical methods for the determination of the chemical oxygen demand (COD) in samples with elevated chloride concentrations. The precision and accuraca of test kits commercially available were compared with a German standards method. To avoid a basis in the COD determination, chloride concentrations were eliminated as gaseous chloride or by complexing agent.
