Determination of gaseous acidic compounds by measuring fluorescence after their reaction with tetra-substituted amino aluminum phthalocyanine.

Abstract

Based on the fluorescence enhancement of a red-region fluorescent dye, tetrasubstituted amino aluminum phthalocyanine (TAAlPc), in strongly acidic medium, a new method was developed for the detection of four strong acids (HCl, HBr, HNO(3) and H(2)SO(4)). Under optimal conditions the linear ranges of the calibration curves were 0.04-0.67 mol/l (HCl), 0.04-0… (More)
