Several classes of synthesized calixarenes bearing several moieties (ether, ester, and amide derivatives), were tested for the extraction of strontium picrates (from aqueous solutions into dichloromethane).128 Only a few of them show appreciable extraction levels. The p-i-butyl calix[6]arene hexa(di-/V-ethyl)amide (CA4) shows a very high extraction level of alkaline earth cations with respect to alkali metal cations. Moreover, dealkylation of the calix[6]arene hcxa(di-/V-cthyl)amidc (CA5) decreases the extraction of both sodium and strontium. As this decrease is much more important for sodium than for strontium, the Sr/Na selectivity, which increases from 3.12 to 9.4, is better than that achieved for DC18 derivative under the same conditions (8.7). These results were confirmed by extraction of strontium (5 x 10 4 M) from 1 M HN03 solutions, where it was found that p-t-butyl calix[4]arene tetra(di-N-ethyl) amide (CA2) (10 2 M in NPOE) extracts only sodium (DNa = 12.3, DSl < 0.001). [Pg.245]

Increasing the size of calixarenes favors the extraction of strontium and leads to a decrease of sodium extraction. For p-t-butyl calix[5]arene pcnta(di-/V-pcntyl)amide (CA3) (10-2 M in NPOE), DNa = 0.79, DSl = 1.5. For p-t-butyl calix[6]arene hexa (di-A-ethyl)amide (CA4) (5 x 10 3 M in NPOE), DNa = 0.05, DSl=3.8. Under the same conditions (HN031 M), this compound displays higher selectivity than DC18C6. [Pg.245]
