Soil The half-lives of captan in soil ranged from 3.5 d (pH 6.4, moisture content 17.5%) to >50 d (pH 6.2, moisture content 1.6%) (Burchfield, 1959). The half-lives of captan in a sandy loam, clay loam, and an organic amended soil under nonsterile conditions were 10-354, 3.4-587, and 7.0-213 d, respectively, while under sterile conditions the half-lives were 9.4-373, 2.8-303, and 4.3-191 d, respectively (Schoen and Winterlin, 1987).

The Mass Action Model The mass action model represents a very different approach to the interpretation of the thermodynamic properties of a surfactant solution than does the pseudo-phase model presented in the previous section. A chemical equilibrium is assumed to exist between the monomer and the micelle. For this reaction an equilibrium constant can be written to relate the activity (concentrations) of monomer and micelle present. The most comprehensive treatment of this process is due to Burchfield and Woolley.22 We will now describe the procedure followed, although we will not attempt to fill in all the steps of the derivation. The aggregation of an anionic surfactant MA is approximated by a simple equilibrium in which the monomeric anion and cation combine to form one aggregate species (micelle) having an aggregation number n, with a fraction of bound counterions, f3. The reaction isdd...
