The leaching behavior of aldicar among complex Pollution system composed of surfactant SDBS and aldicarb

摘要

The leaching behavior of aldicarb among the complex pollution system composed of aldicarb and surfactant - sodium dodecylbenzenesulfonate (SDBS) was studied by soil column. Distilled water was used to simulate rain in order to obtain the rainfall of 235 mm for each time. Three simulations were carried out successively to give 705 mm rainfall in all. The results of multi- Step leaching experiment showed that compared with control column, SDBS can increase the vertical Distance of aldicarb moving and accelerate the leaching.
