Removal of chlorsulfuron and 2,4-D from spiked soil using reversible electrokinetic adsorption barriers

This work focuses on the application of REKAB (Reversible Electrokinetic Adsorption Barriers) technology to remediate two soil matrixes spiked with 2,4 dichlorophenoxyacetic acid (2,4-D) and chlorsulfuron (CLSF), two herbicides that exhibit a high water-solubility and very different volatility and a...

Los resultados obtenidos después de las pruebas de tratamiento de 15 días se comparan con los obtenidos utilizando la tecnología de lavado de suelo electrocinético simple (EKSF) y se señalaron diferencias muy importantes. Ambas tecnologías son eficientes en la eliminación de herbicidas de los suelos. Sin embargo, mientras que en la EKSF el transporte de pesticidas a los pozos de los electrodos es muy importante y se favorece la evaporación, en particular para la remoción de 2,4-D, en el caso de la REKAB, la retención por el lecho de carbón es el principal mecanismo (40 % y 60% de 2, 4-D y CLSF respectivamente) y tanto la evaporación como el transporte a los pozos de electrodos, aunque significativos, son menos importantes que en el EKSF. Después de los 15 En el tratamiento diurno, solo el 28 % de 2,4-D y el 12 % de CLSF permanecieron en el suelo, ya que las pérdidas por evaporación y contaminantes son menos de la mitad de las obtenidas con la tecnología EKSF.Elsevier202220222017info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttp://hdl.handle.net/10578/29771reponame:RUIdeRA.
