title: Differentiation of mobile and immobile pesticides on anionic clays by 1H HR MAS NMR spectroscopy.
abstract: Adsorbed vs. intercalated MCPA (4-chloro-2-methylphenoxyacetic acid) in highly hydrated clays taken as a soil model were clearly distinguished by 1H HR MAS NMR; adsorbed herbicide gave sharp signals indicating high mobility while intercalated herbicide gave very wide unresolved spectra due to its strong interaction with the solid matrix.
