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 an initial rapid loss due to reversible mass transfer processes, followed by a slow loss due to irreversible reactions.

Fortunately, however, the most potent carcinogens among the aromatic amines appear to possess certain structural identifying characteristics, such as: o one, two, or three conjugated aromatic ring systems, o an aromatic amino group substituted in the position para to the conjugated aromatic system; or o groups, such as methyl, methoxyl, or.

Octanol–water partition coefficient (Kow) is a very valuable parameter with numerous environmental applications, where it is used as a primary characterizing parameter since it represents a measure of the tendency of a compound to move from the aqueous phase into lipids.

Experiments were carried out by batch technique at room temperature (25±1 °C) in 25 ml centrifuge tubes at a constant initial concentration of p-nitroaniline (80 mg/l) in the presence of varying concentrations of other organic acids or bases as ratios of sediment to solution for competitive experiments is 4 g to 20 ml.

The length of time soil remained satiated at the and m depths was negatively correlated with relative elevation (in relation to the nearest depression edge).

You will learn such terms as texture, aggregation, soil structure, bulk density, and porosity as it relates to soils. Sorption of organic contaminants (phenol, p-nitrophenol, and naphthalene) to natural solids (soils and bentonite) with and without myristylpyridinium bromide (MPB) cationic surfactant was studied to provide novel insight to interactions of contaminants with the mineral-adsorbed surfactant.
