CEJUDO-ESPINOSA, E.; VELAZQUEZ-ZEPEDA, A.  e  RODRIGUEZ-VAZQUEZ, R.. Adsorption of atrazine in circular sections of roots of three wetland plants. Rev. Mex. Ing. Quím [online]. 2009, vol.8, n.1, pp.35-39. ISSN 1665-2738.

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 (q_m= 2.035), followed by T. domingensis (q_m= 1.797), and E. pyramidalis (q_m= 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.
