“…Breakthrough points were accepted as the values just before reaching the boron concentration of 1 mg L −1 , which is the maximum permissible concentration for irrigation water. 5 As seen from Table 7, Diaion CRB 05 has the highest breakthrough capacity of 3.74 mg B mL −1 resin and the greatest total capacity of 5.20 mg B mL −1 resin among the adsorbents tested. Consistent with the calculated breakthrough capacities, bed volumes to reach both breakthrough and saturation points for Diaion CRB 05 were obtained as the highest compared with those for Chelest Fiber GRY-HW and Diaion CRB 02.…”

“…While boron concentration ranges from 0.3 to 100 mg L −1 in ground water, it is approximately 4.5 mg L −1 in seawater . High boron concentration in water results from power plants, industrial wastewaters, production facilities, fertilizers, pesticides, and sewage effluents may cause environmental problems . The concentration of boron in soil and irrigation water is usually very low, but it accumulates quickly when the soil is irrigated by wastewater containing boron.…”

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

“…Conversely, boron can be found in the nature in the form of boric acid, polyborates, or borate salt which is present commonly in seawater and minerals. Boron in form of boric acid is an essential micronutrient for the plants and its dosage or elimination of irrigation water is very important for different crops; in addition, water contamination by boron can come directly from industrial wastewater, agrarian products, and municipal sewage . Boron removal methods from aqueous solution are mainly adsorption, ion exchange, and membrane processes .…”

The objective of this work was to synthesize functional polymers, with boron removal properties, from high molecular weight linear polyols based on N‐methyl‐d‐glucamine (NMDG) and polyurethane units as crosslinking reagent. For that, (4‐vinylbenzyl)‐N‐methyl‐d‐glucamine monomer (VbNMDG) was synthesized from vinylbenzyl chloride and NMDG, and subsequently, high molecular weight linear poly(VbNMDG) was obtained by radical free polymerization. Later, polymer dots were obtained from poly(VbNMDG) and urethanization reactions using methylene diphenyl diisocyanate at room temperature. Monomers and polymers were characterized by different techniques (FTIR, DLS, elemental analysis, H1‐NMR). In addition, boron retention properties were studied by diafiltration technique using the azomethine‐H method. It was concluded that synthesis of polymer dots, with high boron retention capacity, can be easily synthesized by procedure described. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

a b s t r a c tA divinylbenzene cross-linked polystyrene resin with amine functional groups (Purolite A170) was grafted with glycidol and characterized as a novel sorbent, GLY-resin, for the oxoborate removal from model solutions and post-crystallization lye. The sorption behavior of GLYresin was investigated using a batch system. The results showed that the sorption was maximal at pH¼ 9.5. The equilibrium was achieved after 24 h. Calculations based on Langmuir model show the monolayer sorption capacity q m ¼1.3 mg/g and the fitted experimental data chemisorption as a dominating mechanism of boron sorption on GLYresin. Boron removal from the solution containing 5 mg B/L and postcrystallization lye having a 9.1 mg B/L was 99% and 80% respectively. The thermodynamic calculations indicated the spontaneous and endothermic nature of the sorption process. The pseudo-secondorder model adequately described the boron sorption on GLY-resin. SorptionÀ desorption efficiency was 100%, which means the boron sorption at next cycle did not decrease.
