| Abstract: | The sorption of a diazocompound on a highly basic anionite has been studied. The analytical properties of the modified adsorbent have been considered. A technology has been proposed for the production of a film membrane Zn-SE utilizing modified amberlite as the ionophore. The composition of the membrane has been optimized and the main potentiometric characteristics of zinc-selective electrode have been determined. The advantages of the proposed Zn-SE construction are explained. |
