Extraction of zirconium from nitric acid by dihexyl N,N-diethylcarbamoylmethylphosphonate

Journal Article · · Solvent Extr. Ion Exch.; (United States)
;
The extraction behavior of Zr from aqueous HNO/sub 3/ was studied using dihexyl N,N-diethylcarbamoylmethylphosphonate (DHDECMP). Distribution ratios were examined as a function of contact time, concentration of solute, acid, and extractant and extaction temperature. It was found that the extractant dependency for Zr is second power. Temperature dependency studies were hindered by an apparent Zr specie change above 30/sup 0/C. Extraction of Zr is strongly NO/sub 3//sup -/ dependent.
