The effect of ionic strength on surfactant-induced unsaturated flow
Abstract
The effect of ionic strength of soil water on surfactant-induced unsaturated flow is investigated for the anionic surfactant DOWFAX 8390. Instrumented infiltration experiments were performed to study the impact of surfactant and ionic strength of the soil-water solution on unsaturated flow. A solution having a measured surface tension of 68 mN/m was prepared with 0.014% w/w DOWFAX using distilled water and applied to the soil column …
