Abstract

Two types of poly(vinyl chloride)(PVC) barium ion-selective electrodes are compared. Each electrode is based on a sensor formed from the tetraphenylborate of the non-ionic surfactant Antarox CO-880 and its complex with barium (tetraphenylborate complex) and uses 2-nitrophenyl phenyl ether as solvent mediator. The first electrode is an original type, fabricated as a classic PVC model, whereas in the second, the PVC sensor material is applied to the outer surface of an epoxy resin and has no internal filling solution. Apart from the fact that the epoxy-based electrode has a longer lifetime, the two types of ISE possess virtually identical electrochemical properties. The electrodes were also assessed for measuring sulphate by analate subtraction.
