SEPARATION OF P-32 FROM S-35 AND FROM SOME OTHER ANIONS ON MgO

The selective adsorption of carrier-free quantities of P/sup 32/ on MgO from dilute solutions of various salts was studied. A few tens of milligrams of the adsorbent accomplished the quantitative separation of P/sup 32/ and S/sup 32/. Sulfates at concentrations higher than 0.5 N affected adsorption. Working conditions, necessary for adsorption yields higher than 80% from mixtures with suifates were sthdied. A possible use in production of P/sup 32/ and S/sup 32/ is suggested. (auth)
