Separation of glycols from dilute aqueous solutions via complexation with boronic acids

Boron removal from aqueous solutions by activated carbon impregnated with salicylic acid

“…Besides, according to literature, dimerical complex in Eq. (6) must occur in this pH level [22,27]. It was thought that the dimerical com- Fig.…”

“…According to this rule, neutral complexes with diols form at lower pH than pK a of boric acid and anionic complexes at higher pH than pK a of boric acid. The reactions of boric acid and borate anion with cis-1,3-diols are given as follows [22,23].…”
