title: Separation of fluoride by rapid diffusion using hexamethyldisiloxane.
abstract: The presence of hexamethyldisiloxane greatly accelerates the diffusion separation of fluoride, making it possible to recover > 97% of radioactive fluoride in one hour at room temperature. Agitation, and concentration of the acid and alkaline solutions, affect the rate of diffusion. The presence of biological material has little effect on the rate of diffusion. Sulphate and phosphate do not diffuse under these conditions.
