Abstract :

In this study, synthesis and studying sensitivity of Nano sensor of zinc magnesium ferrite with common formula of Mg0.5Zn0.5Fe2O4 has been considered. Applied method for manufacturing Nano sensor is co-precipitation method that is a novel method for this combination. Nano sensor structure was investigated using such experiments as X-ray diffraction (XRD(, transmission electron microscopy (TEM) and X-ray fluorescence (XRF). Respectively, XRD experiment confirmed the formation of ferrite phase, TEM image showed nanostructure formation of this ferrite and XRF information reconfirmed correct atomic relation of ferrite. Sensitivity of this Nano sensor was tested using a laboratory system equipped with sensor heater with the ability of temperature control on which Nano-sensor was put, a chamber for injecting various solvents and a connector electronic range that transferred Nano-sensor information to computer and it was analyzed by Lab View software. This system could control temperature and wetness and its volume was 5 litters. This Nano sensor was tested using ethanol, methanol, chloroform, acetonitrile, ammonia and acetone and sensitivity of methanol and acetonitrile was better than others. The best response temperature for this Nano sensor (between 100˚C -300˚C) was 300˚C.
