Role of the Organomineral Gel in the Formation of the Nonsolvent Volume of Soils

摘要

We considered nonsolvent volume(NV)of soils and showed that water absorption from the solution by the double electric layers(DHLs)of noninteracting soil colloidal micelles fails to explain the existing experimental data set.We suggested that the interaction between colloidal particles affects the NV value.We showed that the NV is a phenomenon associated,above all,with the existence of organomineral gel(OMG)structures in soils and with changes in these structures caused by various factors.When an aqueous salt solution is brought in contact with soils,the salt concentration in the solution increases [1-3],which is explained by the existence of the NV of the soils.
