| heal.abstract | The sorption of a hydrophobic pesticide, thiram, on humic acid (HA) occurs via a specific pH-dependent binding of thirarn at the deprotonated carboxylates of humic acid, forming a species thiram-{HACOO(-)} with K = 0.69. Similarly, thirarn was sorbed by two model polycarboxylate-{SiO(2)COOH} materials via the formation of a surface species thiram-{SiO(2)COO(-)} with K= 0.45 between thirarn and the deprotonated carboxylates grafted On SiO(2) particles. In all cases, allowance of presence of bicarbonate at natural concentration caused severe inhibition of thiram's sorption. Oxalate and formate mimic the inhibitive effect of bicarbonate. Theoretical fit of the data showed that the inhibitive effect of HCO(3)(-) is due to the formation of the anionic species [thiram-HCO(3)](-1) (with K= 0.90) which is water soluble and compotes with the bound species thiram-{HACOO(-)}. The same phenomena were observed for the sorption of disulfiram. The specific interaction phenomena reported here bear relevance to the sorption properties of thiram and disulfiram on real soils and, therefore, may determine their environmental fate. | en |
