| Abstract: | Cupric sulphate-urea complex has been prepared in aqueous medium and growth
morphologies of complex and reactants have been compared. Morphology of the
complex is different as compared to those of the individual reactants. UV-vis
spectra of pure cupric sulphate and aqueous solutions of complex prepared in
different cupric sulphate and urea ratio show the maximum shift in λmax
when the molar ratio of cupric sulphate and urea is 1:2. Detailed investigation
of the 1:2 complex has been carried out by IR, powder X-ray diffraction,
thermogravimetry, differential thermal analysis and electron spin resonance
studies. Surface topology of the complex has been studied by atomic force
microscopy and the particle diameter observed by transmission electron
microscopy. Nanosized complex is formed with particle diameter in the range
24-120 nm, while the average thickness of the particle is in the range of 634
-1260 nm. |
