The Hanna Instruments HI 3857 is a Detergents Test Kit; Detergents can enter water and wastewater by discharge of domestic and industrial cleansing waters. The most widely used detergents are linear alkyl sulfonates (LAS) and alkyl benzene sulfonates (ABS): LAS are preferable to ABS because they are biodegradable, thus readily decomposed by microorganisms. The presence of anionic LAS/ABS detergents in natural waters should be below 0.1 mg/L and in raw domestic wastewater in the range from 1 to 20 mg/L.

The aqueous solution containing the detergents is treated with the colored indicator. The reaction product can be extracted in the chloroform layer, while the original dyestuff is insoluble in the organic medium. The intensity of the color developed is proportional to the concentration of the detergents present.
