SYNTHESIS OF NEW AZO REAGENT FOR DETERMINATION OF Pd(II), Ag(I) AND APPLIED TO ENHANCE THE PROPERTIES OF SILVER NANO PARTICLES

This study describes the use of novel azo dye reagent, (L), (E)-5-(4-[(1,5-dimethyl-3-oxo-2-phenyl-
2, 3-dihydro-1H-pyrazol-4-yl)diazenyl)phenyl]-5-ethylpyrimxline-2,4,6 (1H, 3H, 5H)-trione, have been
synthesized between phenoparpetal with 4-aminoantipyrine and characterized by IR,
1H NMR, 13C NMR
spectra and CHNO analysis, as simple, selective and reliable analytical reagent for the determination of
Pd(II) and Ag(I) ions spectrophotometrically. The reagent reacts with ions at pH 4 for Pd(II) and 8 for
Ag(I) and formed colored complexes 1:1 stoichiometry of Pd(II) and Ag(I), which show a maximum
absorbance of 518 and 492 nm of molar ratio absorbitivity 5.331 x 10
3 and 1.025 x 104 L.mol-1 cm-1,
respectively. Fixed optimum conditions were constructed, precision, accuracy, R. S. D. and effect of
solvents. The beers law was obeyed 0.1-3 mg/L. The reagent was used for enhance the properties of nano
silver by ligand exchange reaction on nanoparticles.
