摘要

Degradation of the anionic surfactant sodium lauryl sulfate (C12H25SO4Na, SLS) in its aqueous solutions with concentrations of 0.02-1.1 mmol/L acting as a liquid cathode of atmospheric-pressure dc discharge in air at a discharge current ranging within 20-100 mA has been studied. The products of degradation in the liquid phase have been identified, and the kinetic characteristics of their formation at an initial SLS concentration of 5 x 10(-3) g/L (similar to 0.02 mmol/L) and a discharge current of 40 mA have been determined.
