Quantitative Separation of Calcium, Barium, and Strontium

Abstract: Petroleum ether extraction did not change the composition of the precipitate residue, even in the presence of a water phase.A material of the composition of aluminum diresinate was isolated from size precipitates and sized papers by petroleum ether extraction.Petroleum ether extraction of size precipitates prepared from sizes of 0 to 75% free rosin left a residue of the approximate composition of aluminum diresinate in each case.

“…The determination of the extent and significance of radioactive water pollution requires a prior knowledge of the natural radioactive background and the current levels of gross alpha and beta radioactivity as well as some knowledge of the source of contamination (with respect to the kinds of radioisotopes). Methods have been developed and surveys made on both natural background and artificial radioactivity (11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24).…”

“…Correct this weight for the solubility of barium chloride in 75 ml. of the hydrochloric-butyl alcohol mixture, by adding 2.0 mg. to the weight of the barium chloride (2). Because barytes rarely contains more than a few per cent of strontium, coprecipitation of strontium chloride with barium chloride need not be feared.…”
