【Abstract】 The electrochemical SO 2 sensor worked at the fixed potential and prepared with Nafion membrane as the solid electrolyte was studied. It was observed that after Nafion membrane was treated with H 2SO 4, the water preserving ability of the membrane was increased. In turn, the performance of the sensor became stable. After lifetime test for 4 months, the performance of the sensor deceased slightly. Thus, this kind of sensor may become a gas sensor for the practical application.更多还原
