Abstract

Fiber optic biosensors have many advantages over traditional sensors. For an enzyme based fiber optic biosensor, the sensing performance can be improved by improving the enzymatic activity of the sensing materials. Metallophthalocyanines (MPc) are effective biomimetic enzymes for the catalytic oxidation of pollutants such as phenols and their chlorinated compounds by oxygen. The study on the catalysis of MPc to the oxidation of chlorophenol will be very important to the development of fiber optic chlorophenol sensor. In this paper, Fe(II) phthalocyanine (FePc) was used as a catalyst for the oxidation of 2-chlorophenol (2-CP). The best solution pH for the 2-CP oxidation is pH6.0, and O₂ is oxidant. The oxidation of 2-CP caused the consumption of O₂ and result in a quantitative relationship between the concentration of 2-CP and O₂. A fiber optic 2-CP sensor based on oxygen sensing and mimic enzyme catalysis was prepared and its properties were studied. There is a good linear relationship between the phase delay φ and 2-CP concentration, which was defined by the equation of y = 0.00119x - 0.03267 and R² = 0.997. It has good repeatability and its response time is 16 min.
