| Abstract |
A selective fluorescence sensor for the determination of p-phenylenediamine (PPD) was fabricated from the alizarin-boronic acid adduct with an assistance of surfactant. Basically, Alizarin Red S (ARS) is not a fluorescence active compound. However, fluorescence intensity can be observed when ARS reacted with 4-formylphenylboronic acid (4-FPBA) and provided the boronate ester adduct (ARS/4-FPBA). Upon the addition of PPD, the fluorescence intensity of the ARS/4-FPBA adduct decreased as a linear function of PPD concentrations. Sensitivity and selectivity of this fluorescence sensor were improved by incorporating the sensor molecule into the hydrophobic core of micelles. Various parameters that could possibly affect the fluorescence quenching of boronate ester adducts by PPD were investigated and optimized. Under the optimized condition, the working linear concentration range was found to be 0.03-0.40 mM and the calibration sensitivity was 48 times higher than that from the system containing only buffer solution. |
