Studies on tetra-substituted amino aluminum phthalocyanine as a new red-region substrate for mimetic peroxidase

Tetra-substituted amino aluminum phthalocyanine (TAAlPc) has been synthesized and used for the first time as a new red region fluorescent substrate for the determination of hydrogen peroxide catalyzed by peroxidase or mimetic peroxidase. Under optimum conditions, the calibration graph has a linear range of 0.0-3.0 x 10(-7) mol/L H2O2 with a detection limit of 3.7 x 10(-9) mol/L. The feasibility of TAAlPc as a new promising red-region substrate in practical application has been proven in the determination of H2O2 in rainwater. The proposed method can largely minimize the interference that results from background fluorescence or scattering light and has a high analytical sensitivity.
