Adsorption of Escherichia coli in Different Soils
Adsorption of E.coli on soils determines its availability for movement during runoff events. In this study, adsorption of E.coli is determined in two different soils, a silt loam and a clay loam. Clay loam was found to adsorb significantly more E.coli than silt loam. Clay loam absorbed 81.5% and...

| Summary: | Adsorption of E.coli on soils determines its availability for movement during runoff events. In this study, adsorption of E.coli is determined in two different soils, a silt loam and a clay loam. Clay loam was found to adsorb significantly more E.coli than silt loam. Clay loam absorbed 81.5% and 86.2% of E.coli at low and high initial concentrations respectively whereas silt loam was found to adsorb 39.4% and 75% at low and high initial concentrations respectively. Results show that adsorption isotherm could be represented by linear adsorption isotherm. Distribution coefficient was found to be 0.65 and 3.13 ml/g for silt loam and 4.40 and 6.29 ,l/g for clay loam. The distribution coefficient is dependent on the initial concentration of E.coli. |
