UTILIZATION OF A GREEN ANALYTICAL METHOD FOR THE SYNTHESIS OF ZINC OXIDE NANOPARTICLES
[attachment=49386]
INTRODUCTION
There is always a need for the development of improved methodology and processes but major requirement is that the method should have a positive and green effect on our environment and living organisms.
Miniaturization
Miniaturization is a general aim of the technology development that is taking place to produce smaller, faster, lighter and cheaper devices with greater functionality while using less raw materials and consuming less energy. Research on nanomateriels is a step towards miniaturization of technology that will contribute significantly towards a sustainable usage of raw material and energy and help green technology.
Green Technology
Not a solution to all environmental problems
But the most fundamental approach to preventing pollution and helping humanity.
Microwave radiations are radio waves used as green method
wavelengths ranging from as long as one meter to as short as one millimetre,
frequencies between 300 MHz (0.3 GHz) and 300 GHz.
Microwaves do not contain sufficient energy to chemically change substances by ionization, and so are an example of nonionizing radiation. The word "radiation" refers to energy radiating from a source and not to radioactivity.
Zinc oxide
It is an inorganic compound
Widely used as additive in numerous materials and products including
plastics, ceramics, glass, cement, lubricants, paints, ointments, adhesives, sealants, pigments, foods (source of Zn nutrient), batteries, ferrites, fire retardants, and first aid tapes
AIMS AND OBJECTIVES
To synthesize ZnO nanoparticles using cheaper, Simple and greener Method.
Optimization of parameters for getting smaller and stable NPs with better properties.
Analytical application
Conclusion:
A successful green and fast synthesis protocol has been develop to form ZnO-NPs.
Using safe Microwave radiations and get ZnO nanoparticles in only 3 mints which reduce the time, cost and energy consumption.
The XRD patterns are used for phase identification
ZnO was found to be hexagonal and cubic in structure.
SEM was used for microstructure study and agglomeration Nanoparticles showed small amount of agglomeration.
This paper intends to develop an innovative and more appropriate nanoparticles synthetic procedure and characterization under favorable conditions that helps in environmental application
