1922 Chem. Abstr. 3417 Evidence of salt properties is further verified by identity of negative charges with the no. predicted for the periodic group in which the anionic metal is found.

1928 Jrnl. Chem. Soc. ii. 906 It would..be expected that the tendency to migration of different potentially mobile anions (X) contained in systems otherwise identical would follow the order of anionic stability.

1948 Q. Rev. (Chem. Soc.) II. 312 Although there are many examples of systems in which cationic exchange is known to take place, there are relatively few reports of the anionic exchange. These are almost all in the field of inorganic chemistry. The term ‘anionic exchanger’ is often applied, however, to materials which absorb acid molecules from aqueous solution.

1950 Thorpe's Dict. Appl. Chem. X. 800/1 The anion is the active part of the molecule, hence the term anionic agents. The best detergents are in this class.

1962 Lancet 26 May 1109/2 The drug slowly exchanges with cations (or anions in the case of anionic drugs) in the lumen of the alimentary tract and is then free to be absorbed.

1952 McCutcheon & Speel in H. C. Speel Textile Chem. & Auxiliaries xv. 299 Certain non-ionics can be sulfonated to anionics.

1970 New Scientist 15 Oct. 132/2 Difficulty with perborate and anionics could be foreseen, but the effect of phosphate was unexpected.

1989 Pharmaceut. Jrnl. 16 Sept. 341/2 Transitions due to lipid melting that were removed by the anionics alone were protected by the added non-ionics.
