“…The maximum recovery of Pb was at pH 1.5 in the 1st stage ion exchange, which agrees with the earlier results. 18 Between pH 2.5 and 4.5, Pb recovery was constant in the range of 0.8%. Cu recovery was in the range of 43 to 45% and did not change much with pH.…”

This research studied the selective separation of lead and copper ions in acidic solutions using Puromet MTS 9140 resin with a thiourea functional group. The effects of operation parameters, that is, resin dosage, solution pH, ion exchange time, metal concentration, and temperature, on metal ion exchange were investigated using batch-test protocols. Ion-exchange experimental data were analyzed with Langmuir, Freundlich, and Temkin models. The results demonstrate that the MTS 9140 resin has ion-exchange selectivity for copper ions over lead ions. The ion-exchange recovery of Cu exceeded 95%, while Pb coloading was under 19% with MTS 9140 resin dosage of 0.070 g/mL in the pH range of 2.5 to 4.5. The kinetic studies showed that the ion exchange process could be better described by the pseudo-second-order model for lead and copper ions. The temperature dependence indicates the endothermic nature of the ion-exchange process. The resin also showed potential application as an effective adsorbent for removing heavy metal ions in water or wastewater treatment.

The sulfonation of styrenic polymers often needs harsh reaction conditions, such as concentrated sulfuric acid and elevated temperature. The awkward situation is handled by grafting copolymerization of polar and nonpolar monomers, and essentially the surface wettability between sulfonating agent and matrix polymer is circumvented in the study. Two pairs of dual monomers, glycidyl methacrylate (GMA)-acrylic acid (AA), styrene (St)-acrylic acid (AA), were grafted onto polypropylene nonwoven fabrics (PP) using thermal polymerization, and the resulted fabrics were further sulfonated using sodium sulfite and sulfuric acid, respectively. The microstructure of the modified fabrics was characterized by infrared spectroscopy and scanning electron microscopy. The ion exchange property was verified by copper (II) removal from aqueous solution, and its reutilization was carried out in electrochemical desorption process. The results show that hydrophilic and active monomer AA speeds grafting and sulfonation, but overload of AA will deteriorate copolymerization of GMA, and switch copolymerization chain component due to acylation with benzene ring. Although interfacial compatilizer promotes dual grafting, its overdosing may intensify microphase segregation of the grafting polymers owing to emulsification. The resultant granular polymers will be drained off during functionalization and reutilization processes. The ion exchange fabrics can be applied for treatment of metal ion wastewaters with unique electrochemical desorption feature.

“…The process of copolymerization and characterization were already studied by our investigation group [21,22]. The P(AAm-co-ESS), P(APSA-co-AAc), P(AAGA-co-APSA), and P(AAGA-co-ESS) resins were synthesized on a laboratory scale by radical polymerization using acrylamide and the hydrated sodium salt of 4-styrenesulfonate acid monomers for the P(AAm-co-ESS) resin,2-acrylamidoglyolic monohydrate acid and acrylic acid monomers for the P(APSA-co-AAc) resin,2-acrylamidoglyolic monohydrate acid and 2-acrylamide-2-methyl-1-propanesulfonic acid monomers for the P(AAGAco-APSA) resin, and 2-acrylamidoglyolic monohydrate acid and the hydrated sodium salt of 4-styrenesulfonate acid for the P(AAGA-co-ESS) resin.…”

“…Our investigation group in the past already studied the synthesis and better performance ofP(AAGA-co-APSA), P(AAGA-co-ESS), P(AAm-co-ESS), and P(APSA-co-AAc) cationic ion exchange resins for remotion of metal ions from water, in comparison with the commercial resin Amberlite IRP-64 [21,22]. The aim of this research is to study the cationic ion exchange resins P(AAGA-co-APSA), P(AAGA-co-ESS), P(AAm-co-ESS), and P(APSAco-AAc) for the removal of Cr(III) from aqueous solution and to identify the optimal removal parameters using batch and column sorption-elution methods.…”

Ion exchange resins based on the water-insoluble polymers poly(acrylamide-co-styrene sodium sulfonate) (P(AAm-co-ESS)), poly(2-acrylamide-2-methyl-1-propanesulfonic acid-co-acrylicacid) (P(APSA-co-AAc)),poly(2-acrylamidoglycolic acid-co-2-acrylamide-2-methyl-1-propane sulfonic acid) (P(AAGA-co-APSA)), and poly(2-acrylamidoglycolic acid-co-4-styrene sodium sulfonate) (P(AAGA-co-ESS)) were synthesized by radical polymerization. These polymers were employed to remove Cr(III) from an aqueous solution. The optimum sorption parameters of amount of resin and sorption time were obtained through batchmode sorption tests. Following batch elution tests to identify the best eluting agent. Finally,the column-mode sorption/elution behaviors of ion exchange resins were studied. The ion exchange resins exhibited excellent removal of Cr(III). The P(AAGA-co-APSA) resin exhibited 89.4% removal, while P(AAGA-co-ESS) displayed 88.3%, P(AAm-co-ESS) 86.8%, and P(APSA-co-AAc) 89.3%. The column-mode was studied by theP(AAGA-co-APSA) resingave a breakthrough capacity of 1.5 mg Cr(III)/mL resin in the first cycle. The elution efficiency was almost 100%. The breakthrough capacity was 1.2 mg Cr(III)/mL resin in the second cycle. The elution efficiency was 90.2% in the second cycle.
