Utilizing Sulfide-Selective Membranes with Regenerated Properties in Sensors of Sulfur-Containing Gases

Abstract

The feasibility of utilizing sulfide-conducting solid electrolytes MeS-Ln 2 S 3 (Me = Ca, Ba; Ln = Y, Nd, Gd, Sm, Tm) in sensors intended for analysis of sulfur-containing media is investigated. The design parameters and operation regimes of the sensors are selected. The effect of many-component impurities on the sensors' selectivity is investigated. It is established that the ageing is linked to operation parameters of the sensors and the possibility of regeneration of their optimum characteristics.
