Thorium nitrate solutions of 3 x 10/sup -3/ mole were adjusted to 5.5 to 8.0 in pH with sodium hydroxide and then filtered. The amount of thortum in the filtrate was determined by a colorimetric method using o- arsonophenylazochromotropic acid as a reagent. The solubility of thortum hydroxide was estimated as follows pH = 3.75. Th = 4.32 mg/liter, pH = 4.30, Th = 590 mu g/liter. pH = 4.70, Th = 347 mu g/liter. pH = 5.40. Th = 68.5 mu g/ liter. pH = 6.05, Th = 43.5 mu g/liter, and pH = 7 10. Th = 32.7 mu g/liter. Other factors which control the solubility of thorium hydroxide were discussed. (auth)
