- Scope
- This standard specifies a method for the determination of anionic surfactants in industrial circulating cooling water. This standard is applicable to the determination of anionic surfactants in industrial circulating cooling water with a content of 0.05mg/L-2.0mg/L. This standard does not apply to the determination of anionic surfactants when the concentration of anionic substances such as organic sulfates or sulfonates and cationic substances such as quaternary ammonium salt compounds exceeds 15% and 8% respectively of the concentration of linear alkyl sodium sulfonate.
