Process for the concentration of pesticides using aqueous two-phase systems based on organic solvent and carbohydrates and the product obtained

摘要

The present invention patent (IP) refers to a process for the concentration of pesticides in order to obtain a product with biotechnology.Aiming at the identification and quantification of contaminants in water supply for human or effluents.As a distinguishing characteristic of this process and the product described in this patent application, in relation to the alternatives available in the state of the art.It is the fact that pesticides are partitioned to the phase rich in organic solvent, which is obtained with a high factor of concentration, thus allowing the detection of the same.In nano scale, showing the efficiency of the method / process / technique employed.More specifically, we emphasize that the invention refers to a process that allows us to carry out and obtain the concentration of different pesticides.Use of aqueous two-phase systems characterized by based on organic solvents and carbohydrates.This invention has direct application in the area of chemistry, biology, agronomy, agriculture and the environment.Can also be categorized in the field of a product / chemical process or, more specifically,The method / special process for the preparation of chemical compositions for the detection of pollutants / contaminants / pesticides applied mainly to the area of environmental chemistry.
