new method preparation and spectroscopic characterization of the nano organic reagent derivatives from pyrogallol and its complex with iron (III)

In this research, the nanoorganic reagent 4 (4-sulphophenylazo) pyrogallol was prepared by method of forming diazonium salt in an acidic medium coupling compound sulfadiazine with pyrogallol. The complex iron (III) also prepared. and were diagnosed through electronic spectrometers, UV-Visible Spectrophotometers, IR, X-ray diffraction measurements, XRD, 1H-NMR-C13-NMR measurements. effect solvent, acidity function, metal ratio 4-SPAP studied, solid from transitional elements depending on optimal conditions concentration molar at pH metal. calibration curve determined. Where detection limit (LOD) 2.2 ppm quantitative (LOQ) 7.4 ppm.
