Abstract:
A series of novel ladder-type poly(azomethine amide)s (PAMs) were
prepared from new azomethine containing carboxylic acid monomer (TCA) with
simple aromatic diamines and aromatic diamines with thiourea groups (TDAs) by means of
phosphorylation polycondensation reaction. Molecular weights of the polyamides
were evaluated viscometrically, and the inherent viscosities were in the range of 0.31 - 0.58 g/dl. These
ladder-type polymers were not freely soluble in common organic solvents.
Structure of monomers and polymers were confirmed using FT-IR, 1H-NMR
and 13C-NMR spectroscopic analysis. Removal of Cu2+ and
Cd2+ from aqueous solutions by adsorption onto the polyamides was
investigated. The effect of pH, initial metal ion concentrations and contact
time were studied in batch experiments. The polyamides were found to be highly
effective adsorbents for the removal of Cu2+ and Cd2+ metal ions from aqueous solutions. In a mixture of metal
ions, the selectivity order was found to be Pb(II) > Cu(II)
> Cr(IV) > Cd(II).read more
