    Industrial waste contaimnation of water sources is a serious environmental problem. As a result, it's critical to identify metallic contamination in water with precision, sensitivity, and accuracy. In acetonitrile, the fluorimetric parameters of N,N-'bis(2,5-dihydroxybenzylidene)-4,4 '-diamino diphenyl ether (DHDPE) and aluminum complex were determined. In the acetonitrile medium, the best fluorescence intensity of the DHDPE-Al complex was observed at lambda ex = 280 nm, lambda em = 391 nm (excitation and emission wavelengths). For optimum complex formation, the ideal pH, duration, and temperature were 4.5, 20 min, and 25 degrees C, respectively. Within the ranges of 0.027-0.27 and 0.27-2.70 ppm aluminum concentrations, [Al3+]-F.I. Calibration graphs were linear. The fluorimetric aluminum measurement method was applied to diverse water sources using the newly synthesized macro molecular Schiff base DHDPE as the ligand. The aluminum concentration in water inflow to KOSKI (Konya Water and Sewerage Administration) was doubled as a result of the examination when compared to other samples of water.
