Zusammenfassung:Strontium-selective potentiometric sensors with polymeric membranes based on di- tert -butyldicyclohexano-18-crown-6 were developed to control the strontium content in technological solutions of radiochemical industries. The detection limit is shown to be 2 × 10 –6 M, and the slope of the electrode function is 29 ± 1 mV/pSr. The selectivity coefficients of the strontium-selective sensor towards the main interfering ions were determined. It was established that the dose of ionizing radiation at the 10 kGy level does not significantly affect the performance of the developed strontium-selective sensors.
