The aqueous transport of water‐soluble nematicides through soils. I.—the sorption of phenol and ethylene dibromide solutions and the chromatographic leaching of phenol in soils

The sorption isotherms of phenol and of ethylene dibromide in aqueous solutions with sand loams, silt loams and peaty soils are found to be linear. The degree of sorption shows correlations with the physical characteristics of the soils, and sorption coefficients are shown to depend mainly on the soil type rather than on the solute used. The percolation of phenol in aqueous solution through different soil types is shown to follow a chromatographic process, and substantial agreement with a theory of chromatography is found.
