✦ Synopsis

The preparation of a potassium-selective electrode based on a photo-cured polymer membrane containing valinomycin is reported. This electrode has similar response characteristics to one based on PVC with the same neutral carrier. It is suitable for use in flow-injection systems because of its fast initial response and the hardness and mechanical strength of the membrane; nearly Nernstian response is obtained in the range 10 -1-1O-4 M potassium ion.

Flow-injection potentiometry with a combination fluoride-selective electrode is used to determine fluoride in tap water, beverages and urme. Excellent sensitivity (down to 1 pg 1-l) and long-term stability are obtained, with a sample throughput of 30-40 h-l, based on triplicate injections at 120 h-l
