Abstract: Uranium, a heavy metal, is a naturally occurring substance that exists in various chemical forms and plays a significant role in environmental radioactivity. It is found in abundance in sources such as granites, metamorphic rocks, lignite, carnotite, monazite sand, phosphate deposits, and uraninite. While uranium is not as common as other toxic elements like antimony, cadmium, bismuth, and mercury, it is present in higher amounts in the Earth's crust. Uranium can enter the environment through leaching from natural sources, nuclear industry emissions, nuclear weapons use, dissolution in fertilizers, and the burning of coal and other fuels. The chemical and radioactive toxicity of uranium can have adverse effects on the kidneys and lungs. Chemical toxicity may be more important than radiological dose for uranium alone. Uranium's mobility is influenced by its chemical.....

Abstract: The effort to remove methylene blue in waste water had been conducted using adsorption process. 8-HQPHF-III terpolymeric resin has been prepared by condensation of 8-Hydroxy Quinoline (8-HQ), Phenyl Hydrazine (PH) and Formaldehyde (F) in 3:1:4 molar ratio using 2M HCl as a catalyst and was proved to be a good adsorbent for removal of Methylene Blue(MB). The newly prepared terpolymer was characterization and its structural elucidation was confirmed by TGA, XRD, FTIR and 1H-NMR spectral studies. The Dye removal properties of the terpolymer were studied by batch equilibrium method. The effects of various parameters like contact time, initial adsorbate concentration, pH and 8-HQPHF-III doses have also been studied and reported. The adsorption data were found to fit well.....
