Polyamide derived from azo compound of o-amino phenol coupled with acetyl acetone, maleic anhydride acid and p-phenylene diamine were prepared. The prepared polyamide (PA) was refluxed with metal salts of transition metal ions include, $Co^{+2},\;Cr^{+2},\;Ni^{+2},\;Cu^{+2},\;Zn^{+2},\;Cd^{+2}$ and $Fe^{+3}$ in dimethyl formamide (DMF) in different molar ratios. These complexes were characterized and identified by elemental and thermal analysis, IR, 1H NMR spectra. The data showed that PA ligand coordinates with metal ions in abidentate manner through donating N=N and O-H groups. The metal ions are surrounded by coordinated water molecules and anions to establish the geometrical structure of the complexes. The thermal analysis degradation at different temperatures explained the weight loss of hydrated water and the decompositions of complexes until a constant weight loss of metal oxides is obtained.

제안 방법
The aim of the work to prepare a new chelating copolymers containing azo group units as ligating centers with different molar ratios of metal ions, the formed polymer complexes were examined by using IR, and thermal analysis and also by using the atomic absorption spectrophotometer to determine the metal ion content in the solution of the dissolved polymer complex, from these analysis the stability of complexes were identified.
대상 데이터
Reagent grade chemicals were used. Elemental analysis was determined by the analytical unit of Cairo University of Egypt.
