Abstract
AbstractPolymers are widely used materials and are indispensable in handling radioactive materials in fumehoods, gloveboxes, etc. Supercritical fluid extraction (SFE) technique is widely employed for the removal of radioactive contaminants from various matrices using supercritical carbon dioxide (Sc-CO2) modified with suitable ligands as an extraction medium. In the present study, recovery of plutonium from various polymeric matrices, such as neoprene, polyvinyl chloride (PVC) and surgical gloves has been demonstrated using Sc-CO2 modified with n-octylphenyl N,N-diisobutyl carbamoylmethylphosphine oxide (CMPO) in methanol. The matrix was initially subjected to neat Sc-CO2 extraction to prevent co-extraction of organic compounds during SFE of plutonium; in the initial extraction with Sc-CO2, organic compounds added as additives to the polymeric matrix were extracted. In the initial studies, SFE method was developed for the complete recovery of plutonium from simulated polymeric waste matrices. Subsequently...
