INTRODUCTION

Anionic surfactants (A-SAS) represent, by volume, the most important group of surfactants used in cleaning products and the oldest and the largest volume anionic surfactant is soap. In concentrations 0.1 ~ 1.0 mg/L A-SAS become toxic for aquatic environment.

Lumex Instruments provides sensitive and selective fluorimetric method for the measurement of mass concentration of anionic surfactants in water samples using the FLUORAT-02 analyzer.

The method became the Interstate standard for anionic surfactant in water determination; the benefit of the method is that it doesn’t require expensive instrumentation and tedious sample preparation.
