What will the surfactants/detergents test Method 8028 measure?
Surfactants & detergents detected in Hach Method 8028
This test responds to synthetic detergents such as laundry detergents, dish detergents, and car wash detergents. Although the term surfactants refers to compounds that lower the surface tension of water and includes both soaps and detergents, the Hach surfactants test does not respond to soaps. Soaps are salts of fatty acids, whereas detergents are salts of sulfonic acids. The Hach test responds primarily to LAS detergents (linear alkylate sulfonate) and ABS (alkyl benzene sulfonate) detergents.
