“…Thiourea and methyl thiourea based polymers were reported for the removal of Cu 2+ , Cd 2+ and Fe 3+ [20,21]. Recently, Schiff based polymers of chitosen and thiourea based polymers were developed for the removal of Cu 2+ and other metal ions [22][23][24]. Our group is currently concentrating on the synthesis of novel polymers bearing hetero atoms in the polymer back bone for the efficient removal of heavy metal ions [25][26][27][28].…”

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, 1 H-NMR and 13 C-NMR spectroscopic analysis. Removal of Cu 2+ and Cd 2+ 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 Cu 2+ and Cd 2+ 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).

“…Nanoparticles of CuO have been prepared by the alcoho-thermal route described by Hong et al (2002). In the study of Wang et al (2002), it was reported that CuO particles of 3-5 nm dimensions could be prepared by microwave irradiation of an alcoholic solution of Cu(CH 3 COO) 2 in the presence of polyethylene glycol (PEG).…”

The porous texture of CuO obtained from CuC2O4 • 0.5H2O as a precursor, as well as the interconnection between the texture of the initial oxalate and that of the copper oxide obtained, has been studied by physisorption, XRD, XPS and SEM methods. The dimensions of the particle aggregates and the crystalline particles were altered as a consequence of the thermal decomposition of CuC2O4 • 0.5H2O to CuO, and this led to an increase of ca. 1.5-times in the specific surface of the CuO obtained relative to that of the initial substance. The comparatively non-uniform sizes of the intra-aggregate mesopores in CuC2O4 • 0.5H2O were transformed into considerably smaller intra-aggregate mesopores in CuO. A finite increase in the volume of the intra-crystallite pores in CuO was also observed, although this did not change the average size of the intra-crystallite pores in the oxide obtained nor the character of the pore-size distribution with respect to the starting material. In addition, as a result of the thermal decomposition of CuC2O4 • 0.5H2O, the mesoporosity of the prepared oxide also developed. However, the CuO component retained the textural type characteristic of the initial CuC2O4 • 0.5H2O.

“…The catalytic activity of the mixed oxide obtained [16] from the coprecipitated oxalates of Co(II) and Cu(II) was found to be lower than that of the oxides obtained from the mechanical mixture at the same temperature. In recent past, copper ferrite was reported [17] to be generated from the thermal decomposition of coordination compounds containing copper, iron and oxalic anion as ligand.…”
