摘要: A new crystalline inorganic ion exchanger, with the formula Th(HAsO4)2 · H2O, has been prepared by prolonged refluxing of a solution thorium nitrate in arsenic acid. The hydrogen this compound can be completely exchanged Li+ but not larger ions such as Na+ or K+. This singular property, which is due to steric reasons, utilized carry out good separations lithium from other alkali metal ions. Reversibility exchange and chemical thermal stabilities exchanger are also reported discussed.
