    • Induced Desorption of DDT, DDD, and DDE from a Contaminated Sediment 

      Jafvert, Chad; Vogt, Beth; Fábrega Duque, José (1997-03-01)
      Release profiles of p,p′-DDT, p,p′-DDD, and p,p′-DDE from sediment collected from Indian Creek, Alabama, were measured with a gas purge-induced desorption technique and compared to a model developed in this work. DDT entered ...
    • Modeling Abiotic Processes of Aniline in Water-Saturated Soils 

      Fábrega Duque, José; Jafvert, Chad; Li, Hui; Lee, Linda (2000-03-18)
      The long-term interactions of aromatic amines with soils are important in defining the fate and transport of these compounds in the environment. Abiotic loss of aniline from the aqueous phase to the soil phase occurs with ...
    • Modeling Competitive Cation Exchange of Aromatic Amines in Water-Saturated Soils 

      Fábrega Duque, José; Jafvert, Chad; Li, Hui; Lee, Linda (2001-06-01)
      Competitive association to several components of soil through ion exchange processes influences the fate of organic cations in the environment. To examine these processes, the distributions of aniline and 1-aminonaphthalene ...
    • Modeling Short-Term Soil−Water Distribution of Aromatic Amines 

      Fábrega Duque, José; Li, Hui; Jafvert, Chad; Lee, Linda (1998-08-12)
      The applicability of a distributed parameter model for describing the distribution of aniline and α-naphthylamine between soil and aqueous phases at short contact times was assessed. Mass action equations considered in the ...
    • Role of pH in partitioning and cation exchange of aromatic amines on water-saturated soils 

      Li, Hui; Lee, Linda; Fábrega Duque, José; Jafvert, Chad (2001-08-04)
      Predicting the reversible interactions between aromatic amines and soil is essential for assessing the mobility, bioavailability and exposure from contaminated sites. Reversible sorption mechanisms of aniline and α-naphthylamine ...
