Synthesis, Crystal growth and Characterization of Lead acetate zinc (II)Sulphate Material
Abstract
Leadacetatezinc (II) Sulphate Crystal is synthesized by the addition of Leadacetate to Zinc sulphate in equimolar concentration (1:1ratio) to produce larger sized crystal but during the crystallization process a bulk of colourless precipitate was obtained and after filtration the crystals are formed in the filtrate after slow evaporation solution growth technique. Thus formed crystals from the filtrate is kept away and the precipitate formed during the crystallization process is characterized by analysis like Fourier transform infra-red spectroscopy (FTIR), Thermogravimetric analysis (TG-DTA), Scanning electron microscopy - Energy dispersive spectroscopy, power X-ray diffraction analysis and UV-Visible-NIR spectroscopy. The UV-Visible-NIR spectroscopy study reveals that the precipitate thus formed possess good optical behaviour and have higher band gap energy. Functional groups within the material are discerned through Fourier Transform Infrared (FTIR) spectral analysis conducted within the wavenumber range of 600 to 4000 cm^-1. Meanwhile, the thermal study reveals that the material exhibits an optimal level of thermal stability. The powder XRD spectrum shows an increased intense peak with multiple order obtaining higher intensity. The SEM spectrum shows the variation in the surface morphology of the precipitate formed by mixing lead acatate and zinc sulphate. EDS graph confirms the presence of Zinc.
