摘要：

An optical vitamin C sensing probe has been studied based on immobilized 2,6-dichloroindophenol. A kinetic method is employed in the analytical measurement. This optical sensor is shown to respond linearly to vitamin C concentrations in the range 1.6-10 mM at pH 3.0. This linear range varies with pH and temperature, which should be controlled when using the sensor for analysis of vitamin C. A good analytical correlation has been demonstrated for the analysis of vitamin C in samples of orange juice.
