Magnetic Separation of Oxoacid of Boron from Salt-Lake Brine by Synergistically Enhanced Boron Adsorbents of Glucose-Functionalized SiO2 and Graphene
The adsorption separation and extraction of low-concentration boron from salt-lake brine have great significance. Magnetic separation avoids the problem of adsorbent granulation and improves the usage efficiency. The silicon-based adsorbents have attracted interest due to their superior acid and alkali resistance, in which polyhydroxy graphene enhances the adsorption of boron ions. Herein different boron adsorbents, derived by magnetic separation, were developed and characterized by SEM, TEM, XPS, VSM, FT-IR, and XRD analysis. The adsorption-desorption performance of boron adsorbents with different compositions was evaluated. The isotherms and kinetics parameters of the boron extraction were evaluated based on adsorption-desorption tests. The graphene-based magnetic adsorbent (Go-Fe3O4@SiO2@mSiO2-Glu) registered a high boron adsorption capacity of 23.90 mg/g at pH = 9 in the boron solution and 24.84 mg/g for East Taigener salt-lake brine. The Na+, Mg2+, Ca2+, and Cl− ions have little interference with the boron adsorption. The adsorbents exhibit magnetic separation performance and good cycle life. The results showed that acid-alkali desorption solution has little effect on the adsorbents, and the composite of graphene enhances the adsorption of boron ions. The adsorbents developed in this study are promising to recover boron from low-concentration boron-containing salt-lake brines.

Influence of the pH in Reactions of Boric Acid/Borax with Simple Hydroxyl Compounds: Investigation by Raman Spectroscopy and DFT Calculations
The complexation of Boric acid/Borax with hydroxyl compounds is an effective means for the removal and separation of boron in solutions. In this paper, the pH values of the solutions having different molar ratios of boron to hydroxyl compounds including Ethanol, isopropanol, Propanol, 1,2 propanediol, 2,3 butanediol, Glycerol, Xylitol, D‐fructose, D‐sorbitol, and D‐mannitol were determined and analyzed to study the reaction of Boric acid/Borax with different hydroxyl compounds. Solution Raman spectroscopy and DFT calculation were performed to confirm the observations. It was found that the complexation of borate with hydroxyl alcohols follow the order of monohydric alcohols < dihydric and trihydric alcohols < polyols. For polyols, the OH configuration plays very important role in the complexation, and xylitol has the strongest complexation among the polyols at the same molar ratios of boron to polyols.
