What is Anionic Surfactants in Water Testing about?
This document describes an ISO standard method for determining anionic surfactants in water samples by measuring the methylene blue index (MBAS). The method involves forming salts from methylene blue and anionic surfactants under alkaline conditions, extracting the salts into chloroform, and measuring absorbance at 650 nm. Calibration uses sodium dodecylbenzene sulfonate. The method can detect concentrations as low as 0.05 mg/L and is applicable to a range of 0.1-5 mg/L.
