Absorption of Antimony(III) and Indium From Anhydrous Acetic Acid by Ion Exchange Resins

Organic ion exchange resins are a comparatively recent development. In 1935 Adams and Holmes prepared the first ion exchange resin by polymerizing polyhydric phenols with formaldehyde. The condensation product exhibited definite reversible cation exchange properties. The success of this experiment led them to the development of the first anion exchange resin which was prepared by the polymerization of phenylenediamine with formaldehyde. The publication of these experiments inspired many similar investigations leading directly to the manufacture of the numerous ion exchange resins now commercially available
