Abstract

A chemically modified field-effect transistor (CHEMFET) with satisfactory Ag⁺ selectivity is described. The potentiometric Ag⁺ selectivities of CHEMFETs with plasticized PVC membranes based on macrocyclic thioethers have been determined. All the macrocyclic thioethers tested showed silver response and a selectivity towards Ag ⁺ and Hg²⁺ versus other interfering cations. The highest Ag⁺ selectivity was obtained for a 14-membered cyclic tetrathioether with an exocyclic methylene group.
