摘要

研制了基于13X型分子筛阻抗型气体传感器

探测了神经类毒气沙林的相似物甲基磷酸二甲脂（DMMP）。通过交流电压对传感器进行激励

得到其交流阻抗谱的变化

从而实现对不同体积分数DMMP的检测。对0.2×10-6

0.4×10-6和1×10-6DMMP气体分别进行了检测

在1×10-6时（频率为0.01 Hz）电阻的相对变化可达13.2%;同时

分别采用13X型和Cu-β型分子筛作为敏感膜对1×10-6DMMP

100×10-6CO2和饱和蒸汽压下的乙醇气体进行了选择性比较实验。实验表明:基于13X型分子筛膜传感器对DMMP的探测有较好的灵敏度和选择性。

Abstract

An impedance gas sensor based on zeolite 13X for the detection of the nerve agent stimulant DMMP

which is regarded as the stimulant for sarin

is developed.The sensitivity of the sensor for different volume fraction of DMMP gas is determined by exciting with an alternating voltage and determining the impedance response.The sensitivity for 0.2×10-6

0.4×10-6

1×10-6DMMP is investigated

respectively.The normalized resistance for 1×10-6DMMP can reach 13.2% at 0.01Hz.The selectivity of zeolite film 13X and Cu-β is also compared in the detection of 1×10-6DMMP

100×10-6CO2and saturated ethanol

respectively.The experimental results show the good sensitivity and selectivity of the gas sensor based on zeolite 13X for the detection of DMMP gas.
