Study Of Biodirected Synthesis Of Cd/ZnO Nanocomposites And Molecular Imprinting Polymer And Their Environmental Applications

Cadmium-zinc oxide(GCZ)nanocomposite was synthesized by a simple synthetic green strategy.The guava leaves were used as reducing agent for the fabrication of nanocomposites.The functional groups and crystalline properties of the nanocomposite were investigated by FTIR and X-ray diffraction measurements.The optical spectroscopic analysis demonstrated a low value of band gap energy(3.11 eV).The surface morphology and micro structure were affirmed with scaning electron microscopy and high resolution electron microscope.The particle size of GCZ nanocomposite was acquired in the range of 20-50 nm.The photocatalytic degradation execution of GCZ nanocomposite was fundamentally improved and their productivity was accomplished to 99.57,95.2 and 94.3%,visible light and UV light illumination for the degradation of RhB dye in very short time.These experiments show that the Cd-doped ZnO nanocomposite could be utilized as a productive photo catalyst for the degradation industrial toxic compound.On other hand,we presented a general convention to manufacture molecular imprinting polymer network of Fe3O4@PDA/S.A/PEI for the separation of shikimic acid.The composites were characterized by Fourier transform infrared spectroscopy.Besides,the adsorption tests demonstrate that the resultant materials have extraordinary affinity and selectivity towards shikimic acid over structurally related compound.The viable strategy proposed in this work may give a new magnetic recoverable molecularly imprinted polymers material for the recognition and separation of shikimic acid.The investigation offer new opportunity for the fabrication of such type of novel compounds for purification and separation purposes.
