Interactions Between Escherchia coli and the Colloids of Three Variable Charge Soils and Their Effects on Soil Surface Charge Properties

摘要: The adhesion of Escherchia coli (E. coli) to the colloids three variable charge soils and its effect on surface properties potassium adsorption these soil were investigated. isotherms E. by can be described using Langmuir equation. amount adhered varied with type followed order: Ultisol from Guangxi > Oxisol Yunnan Jiangxi. iron aluminum oxide contents CECs are important factors affecting colloids. relatively lower higher CEC Jiangxi led compared Yunnan. decreased increasing pH, which was consistent results predicted DLVO theory. made zeta potential soil...
