Scope
This standard specifies the determination method of anionic surfactants in recycled water — the methylene blue spectrophotometry method.
This standard is applicable to the determination of anionic surfactants in recycled water with a concentration range of 0.05 mg/L to 1.5 mg/L. For samples with higher concentrations, the sampling amount can be reduced or the sample can be diluted before determination. This standard is also applicable to the determination of anionic surfactants in surface water and wastewater.
