The laboratory study procedure and results are presented in this section to demonstrate the electrokinetic removal of herbicides from soils. 

Rice culture contributes to environmental contamination with pesticides, leading to soil, surface, and groundwater quality degradation, which may have negative impacts on public health and biodiversity. Atrazine, molinate, and bentazone are examples of herbicides of concern. The electrokinetic process is able to remove these herbicides from soils, since they are all mobilized in the soil solution, under the action of an electric held. The case study presented showed the following ... 

This chapter reports on the application of the electrokinetic process to remove herbicides such as atrazine, molinate, and bentazone from soils. The discussion is focused on (a) the assessment of the behavior of atrazine, molinate, and bentazone in soils when submitted to an electric field, and (b) the evaluation of the applicability of the technique to remove atrazine, molinate, and bentazone from soils.
