Abstract:
Adsorption experiments conducted with S‐methyl‐ 14 C‐aldicarb resulted in what appeared to be negative adsorption (exclusion) of the toxicant on Ca− and Al− saturated montmorillonite clays. Calculated exclusion volumes indicated that aldicarb did not penetrate the interlamellar region. Aldicarb was excluded from at least the first 16 layers of water on external surfaces of montmorillonite. Positive adsorption occured with Ca− and Al− saturated illite and kaolinite clays. Equilihration of aldicarb solutions with one acid and two calcareous Vertisols, and with the organo‐clay complexes isolated from these Vertisols, produced negative adsorption isotherms for the acid and positive adsorption isotherm for calcareous adsorbents.
