“Removal of Certain Radionuclides from Liquid Radioactive Waste Treatment Station using Prepared Sorbent Materials"

Abstract

Radioactive liquid waste produced from nuclear power plants, research reactors, and all institutes that use radioisotopes, have some impacts on man and his environment since they possess some radiological effects on living organisms. Therefore, reduction or removal of some hazardous radionuclides from radioactive liquid wastes is of main concern. Sorbent materials such as polymers have raised considerable attention owing to their water absorption and retention properties. Natural polymers including alginate salt have been adopted to be composed with synthetic polymers including acrylic acid and its derivatives. These kinds of materials often present the best properties of each of its components in a synergic way and have high performances of physical, chemical and mechanical properties. So it is used as good adsorbent agents. This thesis aims to remove certain radionuclides namely, iodine, cesium and europium from liquid radioactive waste solution using some synthesized polymers. Three polymers, poly (acrylamide/acrylic acid/sodium styrene sulfonate)(p1), poly (sodium alginate-acrylic acid)(p2) and poly (sodium alginate-acrylic acid-methacrylic acid) (p3)were prepared using Gamma radiation polymerization technique. The work carried out in this thesis is presented in three main chapters, Introduction, experimental and the results and discussion.
