Abstract
A rubidium-selective electrode has been developed by coating a graphit e rod with a PVC membrane containing decylidene bis(4'-benzo-15-crown- 5) ether, which is used as a neutral carrier. This electrode exhibited a near Nernstian response to rubidium in the range 1.0 x 10(-1) to 5. 0 x 10(-5) mol/liter with a slope of 52 mV/pC. The detection limit was 2.0 x 10(-5) mol/liter. This decylidene bis(4'-benzo-15-crown-5) ethe r is a new compound prepared by Sichuan University and has never been used to prepare a rubidium electrode. (C) 1997 Academic Press.
