The NiO and CdO nanoxides as well as the CdO/NiO oxides mixture were prepared in five samples with different concentrations where the ratio of CdO/NiO was [(1: 0), (3: 1), (1: 1), (1: 3), (0: 1)] by using the gel solution using a polyvinyl alcohol solution (PVA) and the samples were platelimbed at (500̊C) for three hours. The structural properties of the prepared oxides resulting from the cracking process were studied. The XRD results show the presence of pure cadmium oxide diffraction patterns in the sample (S1) as well as the pure nickel oxide in the sample (S5) and confirm the presence of the CdO/ NiO oxide mixture in the samples (S2, S3, S4), The results of XRD also show, through calculations, that the specific surface area increases with increasing granular size and decreases with decreasing granular size. XRD calculations also show that the intensity of eruptions decreases as the granular volume increases and increases with decreasing granular size. Optical measurements were taken and absorption spectra at wavelength (215 nm) within the UV range. The results of the optical measurements show an increase in the energy gap of the mixture. Samples were taken for continuous electrical conductivity measurements. It was found that the highest conductivity was the sample (S3) which reached (0.394 S/ cm), and the biological efficacy sensitivity of the samples was tested on six types of bacteria. The samples show varying efficacy on the six types, all of which were highly influencing the samples of the bacteria under study. |
