Abstract (EN): The aim of this work is to address the problem of remediation of soils contaminated with pesticides by using an innovative technique that is friendlier to the environment, and which maintains the soil structure. This technique consists on the application of supercritical extraction (SCE) with carbon dioxide coupled with ultrasound. This innovative method has the advantage of allowing the use of solvents such as CO2, and avoiding the need for organic co-solvents, which is an important drawback to the application of SCE to soil remediation. The obtained recovery for atrazine is higher than the corresponding values for supercritical extraction with CO2, and similar to the recoveries obtained when organic cosolvents are used.
