“…Although the complexation of boron with polyols has been successfully employed as the basis of selective ion exchange [19][20][21] and supported liquid membranes [22] for boron removal, this reaction has not been utilised in RO technology to improve boron rejection. In a pioneering work on this topic, Geffen et al [23] proposed the addition of D-mannitol to the feed solution to increase boron rejection via the complexation between D-mannitol and boric acid.…”

Boron rejection by nanofiltration (NF) and reverse osmosis (RO) membranes in the presence of glycerol, mannitol and sorbitol was investigated as a function of feed solution pH and boron:polyol molar ratio. In the presence of polyols, significant boron rejection improvement was obtained and the extent of the impact was directly related to the stability constant of the boron-polyol complex. Polyols could complex with boron in either the boric acid or borate anion forms; however the complexation between polyol and boric acid appeared to be incomplete. With and without the presence of polyols, boron rejection was strongly pH dependent. The increase in boron rejection due to polyol addition was higher for the NF membrane compared to the RO membrane. A boron:polyol molar ratio of 1:1 appeared to be adequate. The presence of polyols did not cause any observable membrane fouling. Results reported here suggest that the addition of polyols could allow NF membranes to be effectively used for boron removal.

“…Ion-exchange processes with strong base anion-exchange resins are effective for boron removal, but all other ionic species are also removed, rendering the operation uneconomical if boron is considered as the only objectionable constituent. Boron-specific resin Amberlite IRA-743 with sorbityl functional groups [that is, R-CH 2 -N(CH 3 )-C 6 H 8 (OH) 5 ] forms complexes with boron and is highly specific. Using this resin, it is possible to reduce water's boron concentration below 1 mg L Ϫ1 [1,3,4].…”

“…As for adsorption with magnesium oxide, this process may be suitable for the treatment of low boron concentration. Simonnot et al [5] reviewed the use of Amberlite IRA-743 and discuss the main processes, which are especially appropriate to separate boron compounds from very dilute solutions. Indeed, many processes based on adsorption on different materials or ion-exchange resins, solvent extraction, membrane fil-tration, and reverse osmosis were evaluated for the treatment of liquid phases of low boron concentration.…”

“…Boron is widely distributed in surface and ground waters, occurring naturally or from anthropogenic contamination, mainly in the form of boric acid or borate salts [1]. Water contamination by boron is one of the widespread environmental problems, since even a few parts per million present in irrigation water can cause stunting of plant growth.…”

“…These resins have macroreticular crosslinked polystyrene matrices, on which NMDG is chemically fixed. However, their main disadvantage is slow kinetics in the boron uptake, despite their high specificity to boric acid in neutral pH regions [1,8]. Jyo et al reported chelating fibers having poly-ol groups for boron adsorption [9].…”

A chitosan resin derivatized with N-methyl-D-glucamine (CCTS-NMDG) wassynthesized by using a cross-linked chitosan (CCTS) as base material. The N-methyl-D-glucamine (NMDG) moiety was attached to the amino group of CCTS through the arm of chloromethyloxirane. The adsorption behavior of 59 elements on the synthesized resin was systematically examined by using the resin packed in a mini-column, passing water samples through it and measuring the adsorbed elements in eluates by ICP-MS. The CCTS-NMDG resin shows high ability in boron sorption with the capacity of 0.61 mmol ml -1 (= 2.1 mmol g -1 ). The sorption kinetics of this resin was faster than that of the commercially available resins. Other advantages of the synthesized resin are: (1) quantitative collection of boron at neutral pH regions, (2) complete removal of large amounts of matrices, (3) no loss of efficiency over prolonged usage, (4) effective collection of boron in wide range concentration using a mini column containing 1 ml resin, and (5) complete elution of boron with 1 mol l -1 nitric acid. The resin was applied to the collection/concentration of boron in water samples. Boron in tap water and river water was found to be in the range of 6 to 8 μg l -1 . The LOD of boron after pretreatment with CCTS-NMDG resin and measurement by ICP-MS was 0.07 μg l -1 and the LOQ was 0.14 μg l -1 when the volume of each sample and eluent was 10 ml.
