以 Triton X- 1 0 0为表面活性剂 ,通过溶胶 -凝胶方法 ,把一种混合指示剂包埋在多孔玻璃薄膜上制成 p H传感器 .该传感器的 p H颜色变化范围为 1 .0～ 1 0 .0 ,同时它还具有非常低的渗漏性、很好的重现性和机械、化学的稳定性
Using Triton X-100 as a surfactant, a hybrid indicator was embedded in a porous glass film by a sol-gel method to make a p H sensor whose p H color ranged from 1.0 ~ 1 0 .0, at the same time it also has a very low leakage, good reproducibility and mechanical, chemical stability
