Modeling of kinetics of pertechnetate removal by amino-functionalized glycidyl methacrylate copolymer

A novel macroporous polymer–inorganic nanocomposite as a sorbent for pertechnetate ions

“…[12][13][14] The sorption ability of PGME-deta towards pertechnetate anions was also investigated. 15,16 In this study, magnetic macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) copolymer (mPGME) was prepared by suspension polymerization, functionalized with diethylenetriamine (mPGME-deta) and tested as a potential technetium-99 sorbent in form of pertechnetate ion (TcO 4 À ) from aqueous solutions. The morphology, chemical and physical properties of mPGME and mPGME-deta were evaluated using Fourier transform infrared spectroscopy (FTIR) analysis, mercury porosimetry, scanning electron microscopy with energydispersive X-ray spectroscopy (SEM-EDS), atomic force microscopy (AFM) and SQUID magnetometry.…”

Solution and solid-phase halogen and C–H hydrogen bonding to perrhenate

“…4 The metastable form of technetium 5 and its long half-life 6 decay product 99 Tc are standards for radiolabeling 7 and in situ radiotherapy. Considering the high mobility of 99 TcO 4 − , its stability, 8 and increasing production, 9 the need for synthetic receptors to function as strong and selective chelating agents, liquid-liquid extractants, 2 and ion-exchange stationary phases 10 is pressing.…”

Electrochemical behavior of palladium modified amino-functionalized macroporous copolymer

“…In that manner the polymer contributes to the electrochemical response of the investigated composite material. Amino-functionalized poly(glycidyl methacrylate-coethylene glycol dimethacrylate) (PGME) has ability to absorb heavy metals (Cu(II)) [11], Cr(VI) [12,13], Mo(VI) [14], Tc(VII) [15], depending on pH through several mechanisms, such as chelation, electrostatic interactions or ion exchange [16]. In this manner palladium cluster of nanometer dimensions can be formed on PGME.…”
