Comparación de diferentes técnicas para la detección y remoción de glifosato y 2,4-diclorofenoxiacetico presentes en las aguas residuales.

Abstract

Glyphosate and 2,4-dichlorophenoxyacetic are the most widely used and commercialized herbicides in the world due to their high effectiveness in weed control. The indiscriminate use and its environmental impact have promoted the analysis of its physicochemical properties, the different ways in which these herbicides could contaminate water sources and the analysis to implement techniques that help detect and remove those organic compounds that are present in the plants. wastewater from the agro-industrial sector. This work was carried out in order to compile the techniques currently used to detect and remove glyphosate and 2,4-dichlorophenoxyacetic acid from wastewater, as well as to study the physicochemical properties of these compounds and their possible contamination routes to the water resource. The different detection techniques were compared evaluating detection limits, recovery percentages, treatment times, costs and environmental impact for the two herbicides. Similarly for removal techniques, estimating efficiency, treatment times, advantages and disadvantages, and environmental impact.
