Question
Which surfactants or detergents will the Hach Method 8028 detect?
Summary
Surfactants & detergents detected in Hach Method 8028
Answer
Surfactants, Anionic (Detergents)-Crystal Violet Method 8028_DOC316.53.01138 responds to synthetic detergents such as laundry, dish, and car wash detergents. Although the term surfactants refers to compounds that lower the surface tension of water and includes both soaps and detergents, this test method 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.
