Method for distillation of sulfur for the preparing radioactive phosphorus nuclide

A method for distillation of sulfur to prepare radioactive phosphorus nuclide includes the steps of: charging powdered sulfur into a target tube (10) designed to have an upper and a bottom neck (11,12); degassing the target tube to form a vacuum therein, followed by heating the upper neck (11) to se...

Zusammenfassung:A method for distillation of sulfur to prepare radioactive phosphorus nuclide includes the steps of: charging powdered sulfur into a target tube (10) designed to have an upper and a bottom neck (11,12); degassing the target tube to form a vacuum therein, followed by heating the upper neck (11) to seal the target tube (10); irradiating neutrons into the sealed target tube (10) to produce radioactive phosphorus nuclide; heating a distillation zone to distill the remaining unreacted sulfur; and cleaving the target tube (10) at the bottom neck (12) to separate the distillation and the cooling zones from each other, the separated zones containing the radioactive phosphorus nuclide and the unreacted sulfur, respectively, whereby the radioactive phosphorus nuclide of high purity can be prepared while the sulfur can be recovered at high efficiency.
