Copper (II) Hydroxide nano particles were synthesized via chemical co-precipitation method from Copper Sulphate and Sodium Hydroxide. Structural and compositional properties were characterized by XRD, SEM, FTIR and UV spectroscopy. XRD confirmed the preferential growth of Copper (II)Hydroxide nano particles that width is 33.42nm. The SEM image shows the synthesized Copper (II) Hydroxide show well crystallized particles with plate-like morphology. The FTIR spectrum is used to study the stretching and bending frequencies of molecular functional groups in the sample. From UV spectrum, the band gap of Copper (II) hydroxide nano particles is found to be 4.5 eV. From AAS studies, it is found that the absorbance is directly proportional to the concentration. The linear fit indicates that Copper (II) Hydroxide nanoparticles have been distributed in proper proportion.

Nano particles of Aluminium phosphate have been prepared by chemical co-precipitation method. The particle size and crystal structure of Aluminium phosphate nano powders are characterized by X-ray diffraction (XRD).The surface morphology of the sample is studied from SEM images. The FTIR spectrum is used to study the stretching and bending frequencies of functional groups in the sample. The absorption spectra of the sample are recorded in the UV range. From the analysis of absorption spectra, Aluminium phosphate is found to have a direct band gap of 5.41eV.
