摘　　要：选用淀粉一碘化钾法研制二氧化氮芯片式检定管胶体，研究了载体和胶体配比等对胶体性能的影响，并绘制了定量曲线。二氧化氮芯片式检定管的检测下限是0．27mg／m3。芯片式检定管无需手工切割，采用光电识别，读数误差小，可在光线昏暗的环境中使用。In this paper, starch and potassium iodide were selected as discoloring component of chip-like detecting tubes for NO2. The influences of absorbent carrier and ratio of detection agent on the properties of detection agent were studied, and the quantitative curve was drawn. The detection lower limit of chip-like detecting tubes for NO2 was 0.27mg/m3. Chip-like detecting tubes could be used with no hand-cut, photometric recognition and less reading error in environment with dim light.
