Method for determining the concentration of non-ionic surfactants in an aqueous solution by excitation-emission fluorescence spectroscopy based on the enhancement of the fluorescence of 6-p-toluidino-2-naphthalenesulfonic acid
Résumé
The present invention relates to a method for determining the concentration of a nonionic surfactant in an aqueous solution by excitation-emission fluorescence spectroscopy based on the enhancement of the fluorescence of 6-p-toluidino-2-naphthalenesulfonic acid (TNS), the use of said method for optimizing the consumption of a surfactant in a wastewater treatment process and a soil remediation process comprising said method.
