Extraction capacity of diglycolamide derivatives for Ca(II), Nd(III) and Zr(IV) from nitric acid to $$n$$-dodecane containing a solvent modifier

Sasaki, Yuji ; Zhu, Z.-X.; Sugo, Yumi; Suzuki, Hideya*; Kimura, Takaumi 

In order to evaluate the extraction property of the new extractants, diglycolamide(DGA) compounds, we investigated the maximum extraction of di-, tri-, and tetravalent metal ions using the system of nitric acid and n-dodecane. Limits of metal concentration (LOC) for Ca(II), Nd(III) and Zr(IV) influence strongly on HNO$$_{3}$$ and the extractant concentration. On the purpose to raise the LOC value, we employed the modifier of solvent, N,N-dihexyl-octanamide(DHOA) and DGA with the long alkyl chain, and examined. It is evident that LOC increases with DHOA concentration in n-dodecane and the length of alkyl chain attached with N atom of DGA. The stoichiometric values of LOC(Zr) estimated from the extraction reaction is obtained by using the extraction condition: tetraoctyl-DGA/ 1M DHOA+n-dodecane and 3M HNO$$_{3}$$.
