摘要：以纳米Au膜材料为核心反应器,用硫化氢气体代替口腔呼吸气来检测巯基化合物的浓度变化,实验采用桥式电路,以复射式直流检流计作为测试手段,以电流显示读数。进而以不同的Au膜粗糙度和不同的Au膜厚度分别对硫化氢的浓度进行测试,同时,对比实验数据探索吸附规律。结果表明:在良好的控制条件下,气体体积分数与测试结果成线性关系。
The nanogold film is used as core reactor to cletect the concentration of sulphydryl compounds, hydrogen sulfide is used instead of oral odorgas. The experiment is adopted by electric bridge; the results are measured by galvanometer and showed by current. Furthermore, the concentrations of hydrogen sulfide are tested on the substrate with different film roughness and with different film thickness. At the same time, the data are compared to obtain the rule of adsorption. Under the suitable control conditions, the volume fraction of the gas is linearity with the experiment results.
