The behaviour of dissolved boron and silicon during mixing of sea and river waters has been studied in two surveys of the estuary of the River Alde in Suffolk, England. Removal of approximately 25 30 per cent was found for both elements. This appears to be the first report of estuarine removal of dissolved boron. The extent of removal of silicon in the Alde is

Boron ions have long been known to form complexes with the cis diol group of a polysaccharide. Konjac glucomannan KGM which is one of polysaccharides was used to remove dissolved boron in this study. KGM forms a complex with boron, but does not remove boron from contaminated waters as well as other polysaccharides because of its high water solubility.

20 02 1997  Boron is effectively removed from brine, including lithium containing brines, by acidifying the brine to a pH of 0.1 to 6.0 and then contacting the brine with an extraction medium comprising at least a diol having 6 to 20 carbon atoms in an aromatic solvent. The extraction medium may also contain high aliphatic alcohols and/or a phase modifier.

01 03 2020  Boron B, normally present in ground water and sea water, is a vital micronutrient for plants, but is also toxic in excessive amounts. Under typical conditions, aqueous boron is present as boric acid H 3 BO 3, which is uncharged, making B particularly challenging to remove by mechanisms commonly applicable to removal of trace constituents.
