“…Regarding novel ligand functionalities, the N ‐methyl‐ d ‐glucamine (NMG) group has shown interesting selectivity properties for anion removal. Ion exchange resins bearing NMG functional groups are available commercially and have been used for selective boron uptake . In contrast to the strong base anion exchange resins, which exhibit a higher sorption in which divalent arsenate is the major species (alkaline media), the NMG‐based resin shows a greater sorption at acidic pH values and greater selectivity towards arsenic in the presence of sulfate .…”

This paper is an overview of the versatile polymer materials containing different functional groups at the main or side chain to remove hazardous inorganic species. These materials include water-insoluble, nanocomposite and water-soluble polymers. Water-insoluble polymers and nanocomposites are used in adsorption and ion exchange processes, whereas water-soluble polymers are employed with ultrafiltration membranes in the liquid-phase polymer-based retention technique.

BACKGROUND Development of new selective chelating resins and fibers with large capacity, high selectivity and high sorption rate has received great interest particularly for boron removal from water. In this study, batch and column mode tests were performed to evaluate the abilities of boron selective ion exchange resins, Diaion CRB 02 and Diaion CRB 05, as well as a novel chelating fiber Chelest Fiber GRY‐HW for boron removal from geothermal water containing boron concentration of 10–11 mg B L−1. RESULTS Optimum adsorbent amounts were found to be 4.0 g resin L−1 geothermal water for Diaion CRB 02, 6.0 g resin L−1 geothermal water for Diaion CRB 05 and 8.0 g fiber L−1 geothermal water for Chelest Fiber GRY‐HW. The adsorbents exhibited promising adsorption capacity and their adsorption data for boron agreed well with both Langmuir and Freundlich models. It was found that the sorption kinetics was influenced by particle size of the adsorbents. The rate‐determining step for boron separation from geothermal water was found to be particle diffusion. According to the results of the column‐mode study, Diaion CRB 05 had a breakthrough capacity of 3.74 mg B mL−1 resin, whereas Chelest Fiber GRY‐HW and Diaion CRB 02 had a breakthrough capacity of 2.16 mg B mL−1 fiber and 1.66 mg B mL−1 resin, respectively. CONCLUSIONS These results showed that boron selective chelating resins along with novel chelating fiber could be employed as efficient adsorbents to decrease boron concentration in geothermal water below the permissible level for irrigation water (<1.0 mg L−1). © 2017 Society of Chemical Industry

“…These polymers possess donor atoms such as nitrogen, oxygen, sulfur or phosphorus which can form a complex with metal ions, giving the possibility of retaining ions selectively . The functional groups can interact with metal ions by simple ion exchange or chelation processes and retention phenomena occur at the surface of this type of material without any physical alteration of the ion exchange material …”

New hybrid composites from poly[acrylic acid] (PAA) with Al2O3 oxide was obtained by radical polymerization/sol‐gel process using [3‐(trimethoxysilyl)propyl methacrylate] (TMPM) as organosilane coupling agent. TMPM form covalent bonds between polymer and inorganic phases giving materials with interpenetrating hybrid networks structures. The organic/inorganic hybrids have a good divalent cation retention capacity.
