Standard Test Method for Determination of (Tri-n-butyl)-n-tetradecylphosphonium chloride (TTPC) in Soil by Multiple Reaction Monitoring Liquid Chromatography/Mass Spectrometry (LC/MS/MS)

Importancia y uso:

5.1 This test method has been developed by the U.S. EPA Region 5 Chicago Regional Laboratory (CRL).

5.2 TTPC may be used in various industrial and commercial products for use as a biocide. Products containing TTPC have been approved for controlling algal, bacterial, and fungal slimes in industrial water systems.2 TTPC should not be persistent in water but may be deposited in sediments at concentrations of concern. Hence, there is a need for quick, easy, and robust method to determine TTPC concentration at trace levels in various soil matrices for understanding the sources and concentration levels in affected soils and sediments.

5.3 This method has been used to determine TTPC in sand, a commercial top soil, and four ASTM reference soils (Table 4).
