摘要：

The adsorption-desorption processes of two anilidic herbicides, alachlor and metolachlor, that can produce residue problems in soils, on two activated carbons commercially available Norit W 52 and Gro-Safe have been studied. Adsorption isotherms are of type H1 according to the Giles classification and fit the Langmuir equation. The results show high adsorption values at low concentrations: the adsorption capacity of Norit was always greater than Gro-Safe one and the affinity for the carbons was higher for alachlor than for metolachlor. In all cases we can suggest the formation of a monomolecular film of herbicide adsorbed on the two charcoals considered.
