Synthesis and development of porous chelating polymers for the decontamination of nuclear waste

Synthesis and Characterization of Some Phenolic Resins for the Selective Removal of Radiostrontium

“…We have recently reported the results of our detailed investigations on the uptake of Cs"^ by such resins [1]. Studies on the preparation and properties of Sr^"^-selective phenolic resins, particularly those incorporating iminodiacetic acid as a pendant chelating functional group, have also been reported in the literature [2][3][4]. The present communication deals with the Sr^ uptake behaviour of synthetic polymers prepared from monomers containing phenolic -OH groups in ortho Position.…”

Removal of strontium from aqueous solutions and synthetic seawater using resorcinol formaldehyde polycondensate resin

“…Resorcinol formaldehyde (RF) resin is an effective phenolic resin which is formed by the polycondensation of resorcinol and formaldehyde in alkaline solution [23]. Commercial phenol formaldehyde resinssimilar to RF resin -were utilised to treat low and high level alkaline radioactive wastes [24], as well as laboratory synthesised phenol formaldehyde resins for the removal of both Cs and Sr from radioactive wastewaters [25]. Previous research reported that the phenol formaldehyde resins that are similar to RF resin were generally conditioned with alkaline solutions.…”

Copper complexed polymer carriers for IgG adsorption

“…Nonporous or porous polymer micro beads with an average diameter of usually more than 100 lm are most suitable for these applications. Since porous micro beads can provide increased surface area available for attachment of ligands they can be preferentially utilized for specific adsorption [26].…”
