AbstractThree different smectites (SAz, STx and SWy), sepiolite (S) and palygorskite (P) samples as well as lepidocrocite (L), goethite (G) and hematite (H) samples were used to elucidate the appropriated mechanism of interaction with maleic hydrazide (MH) as influenced by the diverse characteristics of the soil minerals surface. Adsorption and desorption data were fitted to the Langmuir and Freundlich equations from which the adsorption capacities and reversibility were evaluated. The results of the present study let us conclude that: a) MH adsorption on iron oxides, fibrous clays (S and P) and SAz and STx smectites (high layer charge) occurred on external surfaces being the corresponding desorption quite reversible and b) MH adsorption by smectite SWy (low layer charge) occurred as above but also in the interlamellar space (SWy) and its desorption was not reversible.
