Abstract

The process of electrodialysis concentrating of lithium chloride from its solution in n,ndimethylacetamide
was studied. Mathematical model of electrodialysis concentrating in the aprotic
solvent medium was verified. Transport characteristics of membrane pairs, such as current efficiency,
diffusion and osmotic permeability and transport number of solvent, were defined. It is shown that the
transfer of n,n - dimethylacetamide (DMAA) through homogeneous and hybrid organic-inorganic
membranes is occurs with the solvation shells of the lithium ions, and in the form of the electroosmotic
transport of free DMAA
