Paper Title:
Effect of Surfactants on the Adsorption of Fluazinam in Soils
  Abstract

Soil contamination with pesticide has caused critical environmental and health defects and increasing attention has been paid for developing innovative technology for cleaning up this contamination. In this study, the effects of cationic surfactant cetyl trimethyl ammonium bromide, anionic surfactant sodium dodecylbenzenesulfonate, and non-ionic Tween 80 on the adsorption of fluazinam at the concentration of 1/2 CMC, 1 × CMC and 2 × CMC in three soils were evaluated by using batch equilibrium experiment. The K values followed the order as: S1 > S2 > S3 in absence of surfactants. The use of a nonionic surfactant considerably weaken the fluazinam retention, while that of cationic surfactant has the reverse trend. The effects of anionic surfactant on the adsorption of fluazinam in soils is related to soil physicochemical properties and anionic surfactant concentration. These results are of practical interest in developing effective surfactant remediation technology for fluazinam contaminated soils.
