Adsorption of polyvinyl alcohols by montmorillonite

The Adsorption of Poly(Ethylene Glycols) on Clay Minerals

Abstract Poly(ethylene glycols) of molecular weights 200 to 20000 were strongly adsorbed on montmorillonite from aqueous solution. Free energies of adsorption calculated from th...

Organic Materials Which Stabilize Natural Soil Aggregates

Abstract The effect of periodate followed by sodium borate treatment on the stabilities of prewet soil aggregates has been determined by a permeability technique and by wetsievi...

INFLUENCE OF ORGANIC MATERIALS ON THE DETERMINATION OF THE SPECTFIC SURFACE AREAS OF SOILS

Summary The surface areas of a number of soils have been determined before and after removal of organic matter by treatment with hydrogen peroxide. The external area as determin...

Changes in some physical properties of the surface of an impoverished red-brown eath under pasture

The effects of growing monospecific swards of two grasses and a clover for 3 years on some physical properties of a loamy fine sand have been examined. Increases in the stabilit...
