Abstract
The work demonstrates the prospects of using solid electrolytes of CaY2S4–Yb2S3 within electro-chemical sensors sensitive towards hydrogen sulfide and sulfur dioxide. The range of temperature for the optimum sensor operation is determined: 600–900 K. It is found that the suggested solid–state electrochemical sensor allows determining sulfur dioxide and hydrogen sulfide qualitatively and quantitatively in the concentration range of 3.0 × 10–9 to 1.0 × 10–5 M and 3.0 × 10–8 to 1.0 × 10–5 M, respectively.
