摘　　要：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。A kind of pH mixed indicators was entrapped in porous glass films prepared by the sol gel method in the presence of a surface active agent Triton X 100. The color response was in the pH range 1 0~10 0. The sensor was also shown to have low coating leachibility, good reproducibility, mechanical and chemical stability.
