Bond formation in electrosorbates—II electrosorption and double layer properties in non-aqueous solvents

摘要: According to the principles outlined in Part I, electrosorption valencies of various systems are summarized for non-aqueous solvents. γ/z-values ions adsorbed electrostatically can be taken as geometric factors, g, which characterize relative penetration into double layer. For different solvents, g increases with increasing layer thickness, d, or decreasing minimum capacity, Cmin. The partial charge transfer, −γ/z, is discussed dependence on difference, |Δχ|, electronegativities metal and substances. Corresponding analysis water, γ/z was plotted |Δχ| methanol DMF Complete transfer observed < 0·3, electrostatic adsorption without takes place large |Δχ|-values. In mean range eg iodide systems, all influence solvation properties solvent qualitatively only. It concluded that strong solvent-ion interaction facilitates adsorption, but enhanced by a interaction, case anion from aprotic
