The catlomc selectlvlty and electrode characteristics of poly(vmy1 chloride) (PVC) membranes based on bls[(3n + 1)crown-n] ethers are dlscussed The electrodes exhibit Nernstlan responses over the sodium ion actlvlty range 1 X 10m5 -1 M and can be applied over the pH range 2-10 The sodium selectlvlty
Potassium ionselective microelectrodes with a tip diameter of 10 pm are described. The ionophore used is 2,2'-bie[3,4-(16-mow-6)-2-nitrophenylc~b~ox~ethyl]~~decane in a conventional mixture with sodium tetraphenylborate, an ether and PVC. The electrode provides Nernstian response over the range 1O-5
