The Formation of Mineral -organic Compouns and Their Effect on the Surface properties of Soil Aluminosilicates

摘要

The effect of pre-adsorbed polyelectrolyte layers on the hydrophilic-hydrophobic propertis of synthetic andnatural aluminosilicates was revealed in experiments on the sorption of water vapor and heavy metals and th edetemrination of wetting.It was shown that the formation of mineral-organic surface ocmpounds as films of diffrent chemcial nature follow different mechanisms,including activated chemosorption.This process results in the creation of moleculr clusters on the surface of soil aluminosilicates,which determien the chemcial properties of themodified surface:energetic and chemical heterogeneity,specific surface,wettability,adsorption capacity,and so on.
