Abstract
Dynamic responses of self-made potentiometric NH3, CO2, and SO2 sensitive gas sensors are followed in the 10−5–5 × 10−3M concentration range. By least squares fitting of potential versus time curves, Dk product values at the diffusion of NH3, CO2, and SO2 through microporous Teflon are calculated. The obtained results are fairly reflected by the behavior of the sensor. Measurements of potential versus time in mixed solutions of CO2 and SO2 with the CO2 sensitive sensor indicate the presence of the interferent. © 1999 John Wiley & Sons, Inc.

NH3, CO2和SO2通过微孔聚四氟乙烯扩散的在线分析
在10−5 ~ 5 × 10−3M浓度范围内，对自制的电位式NH3、CO2和SO2敏感气体传感器进行了动态响应。通过电位-时间曲线的最小二乘拟合，计算了NH3、CO2和SO2在微孔聚四氟乙烯中扩散时的Dk积值。得到的结果很好地反映了传感器的性能。用CO2敏感传感器测量CO2和SO2混合溶液中电位随时间的变化表明存在干扰。©1999 John Wiley &儿子,Inc。实验室机器人与自动化11:224-228,1999
