Physicochemical investigations on the extraction mechanism of some elements and inorganic acids by quaternary ammonium salts
Description
The extraction of rare earth and transplutonium elements, Tl, Pb, Bi, and Po, and also of HNO3 and HCl, with chloroform solutions of cetylpyridinium salts solutions showed that the salts aggregate in chloroform solutions, forming micelles above a concentration of about 10-2M. Surface tension and surface potential measurements proved that cetylpyridinium nitrate is not transferred to HNO3 solutions in the extraction system, while cetylpyridinium chloride is transferred to ECl solutions.
