Področje projekta (angleško): Under the experimental conditions, sulfonates and sulfates are the compounds chiefly measured, but some positive and negative interferences can occur (see clause 10). The method is applicable to drinking water, surface water as well as waste water, e.g. for the determination of the primary degradation of surfactants being under investigation in test systems containing natural or synthetic waste water. This applies for both laboratory scaled and technical waste water treatment plants.
