The uranium-vanadium separation was carried out in the apparatus described in Figure 2. The main difference was in the stripping devices that are connected to the foam column, D, by a glass joint. Test solutions, prepared as described above, were transferred to the foaming vessel, B, provided with a porous septum, e. The nitrogen flow, saturated with water in A , was started, to produce foam. Foam passed first into E, containing 10 ml. of 0.2M Versene solution, then into G containing 10 ml. of 2.ON HCl. Each run, conducted at a gas flow rate of 20 ml. per minute and room temperature

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
