Abstract

An optical fiber sensor was designed and fabricated for the determination of 2-Chlorophenol (2-CP) based on 2-CP oxidation by oxygen with the catalysis of iron(III) tetrasulfophthalocyanine (Fe(III)PcTs). A lock-in amplifier was used for detecting the lifetime of the oxygen sensing film by measuring the phase delay of the sensor head. The linear detection range of the biosensor was 1.0×10^-6 -9.0×10^-5 mol/L and the response time was 226s. The sensor displays high selectivity, good repeatability and stability, which shows good application prospect in the analysis of 2-CP concentration in actual water samples.
