Download » A process for the removal of iron from crude beryllium sulfate solutions as obtained from beryl ore by means of liquid-liquid solvent extraction is described. This method consists of the extraction of the ferric thiocyanate complex from aqueous beryllium sulfate solution of the proper pH with a mixture of tributylphosphate and kerosene.

Fluoride, added before the extraction, successfully masks the beryllium; as little as 3 microg of lithium can be separated from as much as 1 g of beryllium. The lithium is then back-extracted into 0.1M hydrochloric acid and is determined spectrophotometrically with o-(2-hydroxy-3,6-disulpho-1-naphthylazo) benzene arsonic acid, Thoron.

beryllium-against-beryllium sliding contact by a factor of 1. 5 for the swabbed film and by a factor of 2.5 for the ion-plated film. The 500-hour test at 20 amperes dc with the ion-plated gallium film, after about 2 hours of running time, resulted in the lowest noise level of all of the tests (0.01 mS2 peak-to-peak). The average contact ...
Spontaneous ion separation of the scorpionate beryllium complex, TpBeI 1 (Tp = 1-trispyrazolylborate), occurs upon treatment with THF, yielding [TpBe(thf)]I 2, which was characterized by heteronuclear NMR spectroscopy (1 H, 9 Be, 13 C) and structurally characterized by single crystal X-ray diffraction. 2 represents a rare example of a structurally characterized monocationic beryllium complex ...
