Surface| Zusammenfassung: | In the present work conductivity-concentration relationships have been studied by conductometric method of systems macroporous silica adsorbent – solution of 1,1 charge electrolyte as dependent on hydrochloric acid concentration. The content of counter- and co-ions in solid phase was estimated. It was shown that co-ionic mobility can exceed counterionic one at overlapping of duffusion layers in intra-cell solution. A dependence of electric conductivity of functional silica materials on chemical composition and their surface structure was demonstrated. The cause of change in electric conductivity for β-cyclodextrin-containing silicas was found. |
