Highlights

•
We developed methodology for determining of cationic surfactants in surface water.
•
Procedure involves application of solid phase extraction at sample preparation stage.
•
Ion chromatography–conductivity detection was applied at final determination stage.
•
SPE-IC-CD is simpler, cheaper, less time-consuming and labour-intensive procedure than previous applied ( eg. LLE-LC-MS).

Abstract

A new analytical procedure for the simultaneous determination of individual cationic surfactants (alkyl benzyl dimethyl ammonium chlorides) in surface water samples has been developed. We describe this methodology for the first time: it involves the application of solid phase extraction (SPE – for sample preparation) coupled with ion chromatography–conductivity detection (IC-CD – for the final determination). Mean recoveries of analytes between 79% and 93%, and overall method quantification limits in the range from 0.0018 to 0.038 μg/mL for surface water and CRM samples were achieved. The methodology was applied to the determination of individual alkyl benzyl quaternary ammonium compounds in environmental samples (reservoir water) and enables their presence in such types of waters to be confirmed. In addition, it is a simpler, less time-consuming, labour-intensive, avoiding used of toxic chloroform and significantly less expensive methodology than previously described approaches (liquid-liquid extraction coupled with liquid chromatography-mass spectrometry).
