Influence of the amination conditions on the textural properties and chromatographic behaviour of amino-functionalized glycidyl methacrylate-based particulate supports

Kinetics of hexavalent chromium sorption on amino-functionalized macroporous glycidyl methacrylate copolymer

“…The lower degree of conversion was obtained for sample functionalized with diethylene triamine, probably due to a steric effect, which is one of the main problems in polymer functionalization with larger groups [24].…”

Adsorptive removal of technetium‐99 using macroporous poly(GMA‐co‐EGDMA) modified with diethylene triamine

“…38 The literature data support the conclusion that pyrolysis may be an ideal solution for the used ion exchanger, because there seems to be a general consensus that at temperature $ 500 C, the mass percent of solid residue of GMA-based polymers (barring those containing aromatic substituents) is less than 6%. [51][52][53] Spent organic exchangers may also be incinerated solely 54 or in combination with other combustible waste. 55 The incineration of spent resins in atmosphere rich in oxygen brings about oxidation of the initial feed material and a volume reduction factor in the range of 30-100.…”

Functionalization of adsorbent with different aliphatic polyamines for heavy metal ion removal: Characteristics and performance

“…This is largely attributed to the unique properties of PGMA polymer for its good mechanical strength, sustained acid and base resistance, ease of porosity formation, and high reactivity of the epoxy group [15][16][17][18]. Most studies have used ethylenediamine (EDA) as the polyamine for PGMA functionalization.…”
