标准简介：This International Standard specifies a procedure for the determination of the methylene blue activesubstances (MBAS) index, in the ranges 0,05 mg/l to 0,5 mg/l and 0,5 mg/l to 5,0 mg/l, in various watersamples (e.g. ground water, drinking water, surface water, waste water and leachates). Anionic surfactantsare the most important substances showing methylene blue activity.This method is therefore useful forestimating the anionic surfactant content [including anionic surfactants with carboxylate groups (e.g. soaps)] ofwater. Other types of substance may also show methylene blue activity and contribute to the result. On acase-by-case basis, the range of the analysis may be changed and the method used for other concentrationranges provided they cover exactly one decade of concentration units.
