dc.description.abstract | The use of pesticides presents a risk to terrestrial and aquatic ecosystems. For this reason,
the development of strategies to prevent and restore pollution is of the greatest interest, including the
adsorption to organic matter. The aim of the present study was to investigate the sorption/desorption
and kinetics of atrazine, chlorfenvinphos, endosulfan sulfate, and trifluralin onto several raw organic
wastes by batch experiments. Three kinetic models were used to fit the obtained sorption kinetics data
and two to fit the obtained adsorption isotherm data; both the Freundlich and pseudo-second-order
kinetic models described the sorption isotherms well. The desorption study revealed hysteresis in all
cases, showing strong, and not completely reversible, adsorption in most cases, with the exception
of atrazine-sawdust and chlorfenvinphos-sawdust and chicken manure combinations, for which
responses were weak and irreversible. The best kinetic, adsorption and desorption constants were
achieved for the hydrophobic pesticides. With respect to sorption-desorption rates, orujillo was
found to be the best adsorbent for atrazine, while composted urban solid waste was more suitable
for trifluralin and endosulfan sulfate. Sorption constants and simple correlations indicated that, not
only the organic matter content, but also the nature of the organic matter itself, and the pesticide and
adsorbent properties, determine pesticide sorption-desorption. The use of wastes as efficient and
cheap adsorbents for reducing the risk of pesticide pollution is proposed. | es |
