Removal of Some Environmental Pollutants and Radionuclides from Waste Water Using Novel Adsorbents

Abstract

This thesis discusses the issue of the removal of some radioactive nuclides and heavy metals as a result of water pollution using fly ash carbon, which is a low cost and effective to remove various organic and inorganic pollutants from polluted water. Fly ash is produced in large quantities from combustion of fuel in power plants using diesel, coal and other fuels on wide range. Also carbon nanotube was also used as an effective adsorbent which has great potential to be used as an effective sorbent for the metalloid contaminants. In this study, one of the most famous techniques, namely adsorption, was used to remove radioactive elements and toxic metals such as uranium, thorium, potassium, lead, and copper. The thesis consists of six chapters. The first chapter is the introduction, it contains an introduction on water pollution and its challenges; In addition, it contains an explanation of radioactivity and sources of water pollution, whether by radioactive waste or heavy metals and a survey on modern techniques used to remove pollution from water. Moreover, this chapter includes an introduction of the adsorption techniques used in this thesis. It also contains definitions of the materials used. It also contains definitions of the toxic properties of radioactive elements and specific heavy metals. At the end of this chapter, there is a desk survey of the most recent research and data dealing with this issue as well as the most important objectives of this thesis.
