Ultrafiltration of a polymer-electrolyte mixture

Poly(2-acrylamido glycolic acid): A water-soluble polymer with ability to interact with metal ions in homogenous phase

“…The separation process will be successful if the polymer reagent employed meet the following requirements [5]: high affinity towards the target metal ion, inactivity towards the non-target metal ion, high molecular mass, possibility of regeneration, chemical and mechanical stability, low toxicity, and low cost. Considering these requirements, basic, neutral, and acid hydrophilic polymers have been designed and investigated respect to the analytical determination of metal ions [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. These WSPs can be synthesized by different routes such as radical, cationic, and spontaneous polymerization, but the most usual synthetic procedures are addition polymerization, especially radical polymerization, and by functionalizing polymer backbone through polymer-analogous reactions.…”

Removal of Ag(I) and Cr(VI) by Complexation-Ultrafiltration and Characterization of the Membrane by CFSK Model

“…Till date a variety of rigorous, empirical, and intuitive models for complexation-ultrafiltration process have been studied in terms of their predictive capability and applicability. The decision as to which of the membrane filtration models is the most correct in predicting permeation rates is a matter of complexity (19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29). In this study the combined film theory-Spieglar-Kadem (CFSK) model is used to estimate the different solute-membrane parameters.…”

Poly(2‐acrylamido glycolic acid‐co‐2‐acrylamido‐2‐methyl‐1‐propane sulfonic acid): Synthesis, characterization, and retention properties for environmentally impacting metal ions

“…Applications of water‐soluble polymers to the homogeneous enrichment or selective separation of various metal ions from dilute solutions have been reported. Ultrafiltration is the most suitable technique for LPR studies 3–22, 24, 27. For use in homogeneous metal‐ion recovery, the appropriate water‐soluble polymers should present high water solubility, an easy, inexpensive synthesis route, an adequate molecular weight and molecular weight distribution, chemical stability, high affinity for one or more metal ions, and selectivity for the metal ion of interest.…”
