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

Importancia y uso:

5.1 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 water matrices for understanding the sources and concentration levels in affected areas.

5.2 This method has been used to determine TTPC in reagent water and a river water (Table 8).

(A) Solution A: Level 8 stock solution prepared according to Section 12 and at Table 4 concentrations.(B) Solution B: 75 % Acetone, 25 % Water.

Note 1: This test method has been used to characterize TTPC in real world water samples with success and similar recoveries as shown in Table 8.
