“…Although Raman spectroscopy cannot distinguish between "free" borate anions and their ion pairs with cations such as Na + , the Raman spectra reported by Sasidharanpillai et al 14 suggest that one or more sodium-polyborate ion pairs may exist as an important equilibrium species at high sodium borate concentrations and high pH. Two candidates for the polyborate anion in the ion pair are the divalent triborate species B 3 O 3 (OH) 5 2− reported by Zhou et al 91 and the diborate species B 2 O 2 (OH) 4 2− proposed by Sasidharanpillai et al 14 Other polyborate-sodium ion pairs were postulated by Weres (1995) 82 as a means of regressing the Simonson-Pitzer ion interaction model to high temperature osmotic coefficient data, without spectroscopic evidence for their existence. Of all these candidates, the ion-pair MB 2 O 2 (OH) 4 − appears to be most consistent with speciation data from Raman spectroscopy 14 and yields the best fit to the experimental speciation results for sodium borate solutions.…”

“…In a previous publication we reported a comprehensive thermodynamic model for aqueous boric acid and selected alkali and alkaline earth metal borate systems [M n O + B 2 O 3 + H 2 O + HCl, where M = Li, Na, Ca, or Mg] over wide ranges of concentration, temperature, and pressure required to model geothermal fluids, nuclear power reactor chemistry, and extraction and production of valuable industrial materials such as lithium and boron from brine reservoirs and seawaters. This model offers a valuable framework for modeling and predicting the chemistry of boron in the primary coolant of pressurized water nuclear reactors (PWRs). It can also provide a useful simulation tool in lithium mining and production from salars and salt lakes rich in boron, and in boron recovery from such high-salinity liquid mineral resources. , …”

“…Global distribution of boron mineral resources is highly uneven, with approximately 98% concentrated in a handful of countries, notably Turkey (88%), Russia (2.9%), the United States (2.9%), Chile (2.6%), and China (1.8%) [ 7 , 8 ]. Nature hosts approximately 230 types of boron minerals, yet only slightly more than 20 types of ore with B 2 O 3 contents higher than 12% (lower boron grades being associated with higher production costs)—such as borax, kernite, colemanite, ulexite, borborite, pandermite, hydroboracite, and szaibelyite—are used as raw materials for boron products [ 9 , 10 , 11 ]. In China, the predominant source of boron raw materials is the limited szaibelyite mineral resource, constituting only 6.64% of the total boron resources of the country [ 12 ].…”

“…Therefore, the issue of boron extraction is of utmost importance. The processing of water resources, including saline lake brines [6] and industrial effluents, is extremely important for both protecting the environment and recycling resources. Methods used to extract boron from water include chemical precipitation [7,8], acidification [9], membrane separation [10], reverse osmosis [11], extraction [12], ion exchange [13], and adsorption [14].…”
