| 摘 要： | 采用NASICON(Na离子导体)与BaCO_3-Li_2CO_3电极相结合的方式,使新型CO_2传感器得到发展。据观察,其响应时间以及抗水湿性能都有了提高。对于CO_2浓度在1×10~(-4)～0.5这样宽的范围内,500℃时测得的电动势与能斯特方程符合的很好。该元件几乎不受共存的H_2S(10~(-4)),NO_2(10~(-4)),CO(10~(-4)),SO_2(10~(-4)),C_2H_5OH(10~(-4))、CH_4(5×10~(-3))以及NH_3(2×10~(-3))的影响。

| Abstract: | New type CO2 sensor was developed by combining NASICON and BaCO3-Li2CO3 electrode. It was found to be greatly improved in response time and water vapor-resistance. For a wide of CO2 concentration from 10-4~0.5, the electromotive force examined at 500℃ followed a Nemst's equation excellently. The sensor EMF was hardly affected by the coexistence of H2S(10-4)、 NO2(10-4)、CO(10-4)、SO2(10-4)、C2H5OH(10-4),CH-4(5×10-3) and NH3 (2×10-3). |
