چکیده مقاله:
In this study, zinc ferrite nanoparticles with a diameter of less than ۵۰ nm were synthesized. Using XRD (X-ray Diffraction), Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM) the morphology and structure of this ferrite was investigated. The formation of spinel phase in Zn-Mn ferrite was shown by X-ray analysis. SEM photograph has shown spherical shape of nanoparticles and the dimensions of the samples were confirmed by Transmission Electron Microscope (TEM) at the nanoscale. Using the Debye-Scherrer formula, the size of Mn ferrite nanoparticle crystals was calculated to be about ۱۳ nm. To check the properties related to the sensitivity of this ferrite, a fully insulated Plexiglass box was used and placed in it. By injecting ۱ mL of liquid and vapor it, we will have ۲۰۰ ppm concentration of each sample in this box. Then the injected vapored sample in this box is exposed to the ferrite. After this step, the conductivity of the ferrite in a closed circuit was changed. By changing the sample type, amount of this conductivity was varied. Five gases were tested in this project: ethanol, dimethyl formamid, carbon tetrachloride, acetonitrile and acetone. Among these samples the carbon tetrachloride had the best sensitivity performance. Finally, the sensor equation for carbon tetrachloride was extracted by applying different concentrations of it from ۲۰ to ۲۰۰ ppm.
