摘　　要：将溴酚蓝通过溶胶凝胶方法涂覆在裸光纤上,利用模式滤光光纤传感器测定了溶液中的pH值。该光纤传感器显示了良好的稳定性和重现性,当pH在2-8范围内时对pH有响应,且pH在3-6范围内具有较好的线性关系(r=0.991),其响应时间(t95%)为98s。同时考察了不同离子对模式滤光光纤pH传感器的干扰。A mode-filtered light pH sensor was constructed by a bare fiber coated with Bromophenol Blue sol-gel film.The results showed that this sensor had good stability and repeatability,and the linear range of the sensor was from pH=3.0to pH=6.0（r=0.991）with the response time（t95%）of 98 s.The interference of some common cations to the sensor was also investigated by mode-filtered light pH sensor.
