Cilësia e ujit - Përcaktimi i lëndëve me aktivitet sipërfaqësor nëpërmjet matjes të treguesit të Blusë së Metilenit. MBAS.

Water quality - Determination of anionic surfactants by measurement of the methylene blue index MBAS (ISO 7875-1:1984 modified)

Scope

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.
