PROCESS FOR SELECTIVE EXTRACTION OF NITRATES FROM AQUEOUS NITRATE-SULFATE SOLUTIONS

·
OSTI ID:4834102
A process is described for the extraction of nitrate from an aqueous acidic solution containing sulfate. The process consists of intimately contacting the solution with at least one water-insoluble amino compound in the liquid phase whereby the amino compound selectively extracts nitrate from the solution. A quaternary ammonium compound may be used instead of the amino compound. The compounds are a primary, secondary, or tertiary amine having a molecular weight of at least 185, the quaternary compound also has a molecular weight of 185. The amino compounds employed are dodecylbenzyl t-dodecylamine, dodecenyl t-dodecylamine, tridodecenylamine, or dodecylbenzyl di-nbutylamine. The quaternary compound is dodecenyl trimethyl ammonium chloride. This process has particular value in the cyclic uranium recovery process for decreasing cost by saving of the nitrate solutions.
