Uranium isotope separation by continuous anion exchange chromatography
Uranium isotope separation by continuous anion exchange chromatography
A simple, low temperature process for separating uranium isotopes and producing substantially pure uranium isotope fractions from a crude uranium isotope-containing aqueous feed stock is provided. A uranium isotope-containing solution is fed to an anion exchange resin in a continuously rotating annular chromatograph as a suitable eluant is also simultaneously fed to the rotating chromatograph. A Uranium 235, a Uranium 238 and an impurity fraction are recovered from the chromatograph. The substantially pure uranium 235 and uranium 238 fractions may be subjected to further processing, preferably precipitation with ammonium hydroxide to produce ammonium diuranate, and then calcining to form uranium oxide rich in the desired isotope

the same size, are grouped into a countercurrent train. The plant or cascade as a whole consists of a number of trains. Each of these consists of mixer-settlers of different sizes, and the number of stages in the trains varies. The optimization procedure is a four-stage process designed to minimize the whole plant size" what's redox chemstry, countercurrent solvent extration, and shift phase, and what's the solvent extration plant?
ok, as far I understand, this is a batch process like on pharmacy. what's important to know, is that temperatures must be equal or bellow negative 5.º degrees, and the ultrasonic spray dry at 45 Khz. the rdx must be solved with an anti solvent like ethanol acetone , that's the only chemical where rdx (cyclotrimethylenetrinitramine or 1,3,5-trinitro-1,3,5-triazacyclohexane) is soluble.
good morning! welcome back to war! So what about , going a little back, and find out how to make RDX nano explosives )a dollar coin) by spray dry?
An insensitive crystalline high explosive molding powder, usable as a booster HE. The subject insensitive crystalline high explosive molding powder being manufactured by adding the crystalline high explosive, metal or semi-metal particles and a polymer or wax based binder to a solvent to form a solution, spray drying the solution to drive off the solvent, thereby co-precipitating the HE and binder to form granules in which the crystals of HE and metal particles are uniformly distributed in the binder.
