ADSORPTION OF ATRAZINE IN CIRCULAR SECTIONS OF ROOTS OF THREE WETLAND PLANTS
This work reports the adsorption isotherms for the herbicide Atrazine, evaluated in circular sections of dead roots of three wetland plants, Typha domingensis Sagittaria lancifolia y Echinochloa pyramidalis. The adsorptive capacity (mg Atrazina /g of biomass) of each species was S. lancifolia (qm= 2.035), followed by T. domingensis (qm= 1.797), and E. pyramidalis (qm= 1.107). The highest adsorptive capacity of S. lancifolia is related to the elevated lipid content, which could interact with the herbicide. These results provide information about adsorption as a promissory technique to pesticides remediation in flooded areas
