Séparation complète des métaux alcalins par échange ionique

Use of Ion Exchange Resins in Analysis of Rocks and Minerals. Separation of Sodium and Potassium

“…The effect of the elution on iron, aluminum, titanium, calcium, and magnesium was studied individually: 7 meq. of iron, aluminum, and calcium were retained on the column; more than 3.5 meq.…”

Radiochemical Separation of Fission Products from Large Volumes of Sea Water. Strontium, Cesium, Cerium, and Promethium

“…Xiday's ion exchange method (17) for separating rubidium and cesium has been adapted here. Other workers have shown (9,16,17) that rapid and simple separation of cesium from other alkali-metal ions is best done on a phenol-sulfonic type of cation exchanger. Duolite C-3 is such a resin.…”

The Radiochemistry of Potassium

“…(49) Phoaphatea can be removed frau the alkal.1chlorl.de solution by a precipitation either with 'zinccarbonate (52) or vith an FeC13 solution at a contz%lled pH. (66,67) Potissium and sodium were eluted with 0.1~HC1 and the nibidium and cesium were elutad with 1 N HCl. Amberlite IR-1OO resin and HCl have also been used A carrier-freemethod has been "ueed~the mdloactivation analysis determination of tmce @.assium h alka13 carbonates and chlorides.…”
