摘要/Abstract

摘要： 本文描述了一种新的测量二氧化硫的荧光型光纤传感器。溶于内充液的奎宁被用作敏感物,通过气透膜将内充液与水溶液分开。传感器对二氧化硫的响应范围是3×10^-6～3×10^-4mol/L。报道了传感器的重现性、稳定性、响应时间和选择性。用该传感器测定了含二氧化硫的实际样品并与碘量法进行了比较。

关键词: 气敏传感器, SO₂光纤传感器, 荧光测定法

Abstract: Anew fluorescence fiber optic sensor for sulfur dioxide measurement has been described.Quinine dissolving in internal solution was used as a sensitive material.The internal solution layer was separated from the aqueous solution by a gas-permeable membrane.The response range of the sensor for sulfur dioxide is from 3×10^-4 mol/Ldown to 3×10^-6 mol/L.Reproducibility, stability, resp-ponse time and selectivity of the new fiber optic sensor are reported.With this sensor, practical samples containing sulfur dioxide were measured.The results are compared to measurments with iodime-try.

Key words: Gas sensor, Sulfur dioxide fiber optic sensor, Fluorimetry
