• A thiocyanate-selective electrode prepared from a new matrix, Urushi, and tri-n-octylmethylammonium thiocyanate ion exchanger is described. The electrode shows linear potential-activity curve within the range 1.0×10^<-5>-0.56×10^0 mol dm^<-3> ammonium thiocyanate and the slope is about 59mV per decade change in thiocyanate activity. The electrode has a fast response. Conditions for the preparation of the electrode such as ratio of the liquid ion exchanger and Urushi, amount of water in the Urushi and temperature for hardening the membrane are studied. The electrode characteristics of pH dependence and selectivity coefficient are also examined. The Urushi matrix membrane is hard, lustrous and smooth.
