Description

<p>The surfactants included in the PRTR system were detected using the notified analytical method for nonionic surfactants in tap water. False positive results were obtained when N,N-dimethyldodecylamine-N-oxide, an amphoteric surfactant, and sodium polyoxyethylene dodecyl ether sulfate, an anionic surfactant, were present in tap water. To clarify the behavior of various surfactants, except nonionic surfactants, in solid-phase extraction, different elution solvents were investigated. The total recoveries of various surfactants in the toluene and methanol fractions ranged from 60％ to 120％. Simultaneous solid-phase extraction-LC/MS was validated for all the surfactants using methanol as the elution solvent. For various surfactants, except for nonionic surfactants and anionic surfactants, the accuracy (recovery rates) and repeatability of analysis satisfied the criteria in the guideline for the validation of the testing method for drinking water provided by the Ministry of Health, Labour and Welfare, Japan. Thus, this screening method can be useful for determining the presence of various surfactants.</p>
