All acid uranium phosphate, UH2(P04)2 or UO2.P2O5.H2O, is obtained as a gelatinous 23recipitate when ordinarj " sodium phosphate, or excess of sodium metaphosphate, is added to a solution of uranous chloride. It may be obtained in the crystalline form as UH2(P04)2.oH20. Aloy also describes a uranous chlorophosjihate of composition UH2(P04)2.UCl4 (see p. 295). 

Tributylphosphate is also utilized as a defoaming agent and as an extraction agent in the extraction of wet-process acid, uranium, lanthanides and other metals.

Figure 5.7 Titration of an acid uranium mill-tailings solution with a standard NaOH solution. The tailings solution had a pH of 0.9 and TDS =112 g/L. A solution analysis showed that in addition to the important acid species present were HSO4, Fe, and AF. Data and plot from Langmuir and Nordstrom (1995). See Problem 8 at the end of this chapter.

Williams [W3] reported that from 1959 to 1968 thorium was recovered as a by-product of Rio Algom s uranium mill at Elliot Lake, Ontario. Thorium-bearing uraninite ore was dissolved in sulfuric acid. Uranium was first recovered by anion exchange. Then thorium was recovered from the acid solution by solvent extraction with alkyl phosphoric acid, probably di(2-ethyl-hexyl)phosphoric acid. 

BUTENEDIOL or 2-BUTENE-l,4-DIOL or cis-2-BUTENE-l,4-DIOL (110-64-5) C4H8O2 Combustible liquid (flash point 263°F/128°C oc). Contact with strong oxidizers may cause fire and explosions. Reacts violently with oxidizers, aliphatic amines, alkalis, ammonium persulfate, boranes, bromine dioxide, isocyanates, nitric acid, perchlorates, permanganates, peroxides and hydroperoxides, sodium peroxide, sulfuric acid, uranium fluoride.
