“…One or more methods may be applied according to boron concentration in medium. For boron removal, main processes that have been studied are: (1) precipitation-coagulation, (2) adsorption on oxides, (3) adsorption on active carbon, cellulose or clay minerals, (4) ion exchange with basic exchanger, (5) solvent extraction, (6) membrane filtration, (7) use of boron selective resins (Amberlite XE 243, Amberlite IRA 743) [3][4][5][6][7].…”

“…There are also some other boron removal methods but ion exchange process is the most extensively used with some commercial boron selective resins, such as Amberlite XE 243 [9,11,12], the macroreticular resin Amberlite IRA743 [13,14] and some other N-methylglucamine type chelating resins, Diaion CRB-01, Diaion CRB 02 and Purolite S 108 [15].…”

“…When the average level of boron in irrigation waters (generally given as 1 mg l −1 ) is considered, the very high level of boron in the disposed water of Kızıldere makes the use of this water for irrigation purposes impossible. For the investigation of boron removal from Kızıldere geothermal wastewater, Amberlite IRA 743 [14], Diaion CRB 01, Diaion CRB 02, and Purolite S 108 [15] were employed. These resins have common in N-methylglucamine functional group and they just differ in the type of polymer chain and in some of their physical characteristics.…”

A novel sorbent was prepared by the functionalization of an inorganic support material, MCM-41, with N-methylglucamine for the uptake of boron from aqueous solutions prior to its determination by inductively coupled plasma optical emission spectrometry (ICP-OES). Characterization of the newly synthesized material was performed using BET, XRD, TEM, SEM and DRIFTS techniques, in addition to its C and N elemental content. Sorption behavior of the novel sorbent for boron was also investigated and found to obey Freundlich and Dubinin-Radushkevich (D-R) isotherm models. The maximum amount of B (as H 3 BO 3 ) that can be sorbed by the sorbent was calculated from the D-R isotherm and was found to be 0.8 mmol B g −1 of sorbent. The applicability of the new sorbent for the removal/preconcentration of boron from aqueous samples was examined by batch method. It was found that the sorbent can take up 85% of boron in 5 min whereas quantitative sorption is obtained in 30 min. Any pH greater than 6 can be used for sorption. Desorption from the sorbent was carried out using 1.0 M HNO 3 . The sorption efficiency of the new sorbent was also compared to that of Amberlite IRA 743, a commercial resin with N-methylglucamine functional groups. Within the experimental conditions employed, the new sorbent was found to have higher sorption efficiency than the commercial resin. For method validation, spike recovery tests were performed at various concentration levels in different water types and were found to be between 83-95 and 75-92% for ultra pure water and geothermal water, respectively.

“…Among those methods, the ion-exchange processes in which N-glucamine-type chelating resins and fibers have been used are the most extensively studied and reported in the literature [1,2,[5][6][7][8][9][10][11][12][13]. The development of new boronselective chelating resins and fibers with a large capacity, high selectivity, and high sorption rate received great interest for boron removal and recovery from natural waters and wastewaters.…”
