Studies of Scandium in Various Solutions. I. An Ion-Exchange Study of Scandium(III) Chloride and Nitrate Complexes [PDF]
Bulletin of the Chemical Society of Japan, 1966 Abstract The complex formation of scandium(III) with chloride and nitrate ions has been investigated at 25°C. Scandium-46 was employed in conjunction with a cation-exchange resin (Dowex 50W X-12, 100–200 mesh) in the H+-form and the ionic strength was maintained at 4.0 m with perchloric acid.
