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

Abstract

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