The Anionic Surfactant Test Kit (ASTK) provides a sensitive and
reliable on-site method for estimating the level of an anionic
surfactant in water.
Detection and concentration levels of anionic surfactants
(including Aqueous Film Forming Foams (AFFF)) in water are
currently determined by a laboratory-based method utilising
chloroform – a suspected carcinogen – as the extraction
solvent.
The ASTK is a safe alternative which not only avoids the use of
chloroform, but can be used on-site, reducing costs and time.
How does it work?
The ASTK detects the presence of an anionic surfactant and the
concentration estimated by comparison of the top immiscible layer
to a colour strip.
A field water sample is mixed with solutions provided in the
kit, and if the top immiscible layer of the sample appears blue
this indicates an anionic surfactant is present. The blue band is
then compared to the colour strip providing an estimation of the
concentration of the anionic surfactant.
Who will benefit from this?
AFFF users and groups responsible for related environmental
monitoring will find this product rapid, safe and reliable.
Current status?
A commercialisation partner is currently being sought for this new
technology. Interested parties should contact CRC CARE.
