“…However, applications of SLM are limited due to the instability of the membrane (17). Reverse osmosis was another membrane technique applied for boron removal (20)(21)(22)(23)(24). In RO applications for boron removal, it was found that the rejection of boron highly depended on pH and it tended to rise with increasing driving pressure (20).…”

Two selective functional polychelatogens, namely hydroxyethylaminoglycerol functioned poly(glycidylmethacrylate (PNS) and Poly(4-Vinyl-1,3-dioxalan-2-one-co-vinyl acetate) (COP) were synthesized and utilized in polymer-enhanced ultrafiltration (PEUF) to remove boron from the aqueous solution. The effect of operating parameters on boron retention was investigated. PNS was synthesized in three molecular weights to observe the effect of molecular weight in borate retention. Increase in pH increased boron retention for all of the synthesized polymers. Decrease in loading resulted in an enhancement in retention values when COP, medium (PNSM) and the low molecular weight of PNS (PNSL) were used. No significant change was observed in the permeate flux with COP (41 L/ m 2 Á h), PNSL (48 L/m 2 Á h) and PNSM (47 L/m 2 Á h). However, a decrease in the loading led to a decrease in the permeate flux for high molecular weight PNS (PNSH). Conformational changes in the polymer structure were examined using dynamic and static light-scattering. Retention results for all of the polymers were found to be remarkably higher than the literature, when polyvinyl alcohol was used as the chelating agent. Satisfactory retention results were obtained using both PNSL (R: $54%) and PNSM (R: $57%), showing that PEUF can be employed effectively for borate removal using the specifically tailored polymers.

“…Reverse osmosis (RO) and electrodialysis (ED) are two common membrane processes used for boron removal [28][29][30][31][32][33][34]. Due to the chemistry of boron, the boron is in the form of boric acid at natural pH and ED is only capable of removing about 42-75% of boron, in the case of RO treatment, this is 30-40% [31].…”

“…Particularly at low boron concentrations, traditionally applied removal methods such as membrane filtration [8], ion selective resins [9], adsorption [10], electrocoagulation [3], and precipitation [11] can fail to satisfy. Adsorption for boron removal using cheap and easily attainable adsorbent is substantially beneficial, effective, economic, and quite easily applied method principally at low boron concentrations [10].…”

In the present study, boron sorption removal from aqueous solution by batch experiments was performed and the practicability of granular ferric hydroxide (GFH) for boron removal was studied. Box-Behnken experimental design method (BBD) was applied to the data for determination of the effects of important operating parameters such as initial boron concentration, pH, and dose of GFH on boron sorption efficiency. The obtained results from the present study suggested that BBD was an efficient and applicable method to obtain optimum conditions for boron removal from aqueous solution using GFH. The adsorption kinetic studies indicated that equilibrium was obtained as 20 h and about 96% boron removal efficiency was achieved in that time. The sorption process was well described by pseudo-second-order kinetic model. Freundlich isotherm represented a great fit to the data and was applicable model for the present study. Optimum pH and amount of GFH were calculated as 10 and 90 g L −1 for maximum boron sorption efficiency. The results of the present study showed that GFH can be efficiently applied for boron removal from drinking water.
