DTIC AD0611298: STUDIES IN THE HYDROLYSIS OF METAL IONS 33. A MINIATURE SOLUBILITY COLUMN AND ITS APPLICATION TO A STUDY OF THE SOLUBILITY OF RED MERCURY (II) OXIDE IN ACID 3 M NAC1O4 SOLUTIONS

A scaled-down version of a conventional solubility column which uses only about 2 g of solid material is described. It is well-adapted for handling radioactive materials, and was used for radiochemical measurements of the solubility of red mercury (II) oxide in 3 M NaC1O4 solutions in the pH range 1- 5. The presence of Hg(2+), HgOH(+), and Hg(OH)2 as the only mercury containing species was confirmed, and the values for the equilibrium constants were calculated.
