| Abstract: | A model for the adsorption of bacteria to soil particles is described using the physical-chemical Langmuir isotherm and the van't Hoff equation. An example of the use of the model for assessing bacterial movement through soil is provided.Staphylococcus aureus was the sorbate with sorbents of activated charcoal, kaolinite clay, Mendon silt loam, and silica sand. Competitive agents sodium lauryl sulfate, sodium chloride, and peptone were also studied. Peptone was the most successful competitor with the bacteria for sites on the sorbent. |
