mixture indicator
解釋
混合氣成分-
The oxygen sensing properties of the membranes have been studied, the results indicate that the membranes with ru ( phen ) 3cl2 have better oxygen - sensitivity than those with ru ( bpy ) 3cl2, and the membranes with the formamide content of 16 % ( v / v ) and ru ( phen ) 3cl2 content of 2. 10g / l in the precursor mixture have the best structure and quality. the fiber optic gas oxygen sensor with this sensing membrane has a detection limit of 5ppm, a response time of less than 30s, excellent reproducibility and stability. ( 2 ) a new kind of organically modified oxygen - sensitive membrane based on fluorescence quenching was prepared by sol - gel method, using dds and teos as the mixed precursor, rufchenbcla as the indicator
實驗證明:該類敏感膜的tan _ 0 tan值與氧氣濃度存在良好的線性關系;包埋ru ( phen ) _ 3cl _ 2的凝膠膜的氧敏感性相對較好;當甲酰胺為16體積比含量, ru ( phen ) _ 3cl _ 2在前驅體中濃度為2 . 10g l時,制備的敏感膜結構和性能最佳;對氣態氧檢測時,該敏感膜的響應時間小於30秒,檢測下限為5ppm ,具有較好的重復性和穩定性。
