The described method can be used for the determination of the EOX content in unfiltered samples of the following water types: drinking water, groundwater and surface water with a content greater than 3 nmol/l of X or approximately 0.1 |xg/l of Cl. The content of undis olved components, determined in accordance with NEN 6484, may not exceed 100 mg/l. Notes 1. If the content of undis olved components is greater than 100 mg/l, this must be reduced by settling and decanting. 2. For the determination of the EOX content in wastewater, see NEN 6676.
