Summary
The document describes a method for photometric determination of low concentrations of methylene blue active substances (MBAS), i.e. anonic surface active material (chiefly sulfonates and sulfates) in influents and effluents of sewage plants, waste, surface and drinking water. The range of this method is 0.1 to 5.0 mg/l, the limit of detection for solutions of standard surfactants in distilled water, about 0.05 mg/l.
