METHODS AND KITS FOR QUANTIFICATION OF THE CONCENTRATION OF ANIONIC SURFACTANTS IN WATER OR AQUEOUS MEDIA

摘要

The present invention relates to a method and kits for determining the concentration of anionic surfactants in water or aqueous media by promoting the formation of foam attributable to the same and as a function of the period for disappearance of the foam ring formed on the surface of the water or aqueous medium. For this purpose there is added to a sample of water or aqueous medium a promoter of production of foam attributable to the anionic surfactant to which there has previously been added a buffer to maintain the pH during the test period at a value = 6.
