Extraction of oxoanions by tetraalkylammonium salts

Mutual effects of oxo anions in extraction with tetraoctylammonium salts in polar solvents

“…The concentration exchange constants of oxo anions for chloride and nitrate ions were estimated. 1,2 With the use of the exchange constants of chloride ions for bromide and hydroxide ions and published data, [3][4][5][6] it is possible to form a selectivity series for singly and doubly charged anions. For example, this series for singly charged anions is as follows:…”
