DOI: 10.1134/s0040579519050233
Abstract: The results of experiments on preparing pure (marketable) salt from crude salt of ammonium perrhenate are presented; the pure salt is rigidly standardized in elements–impurities and rhenium by recrystallization, sorption, and membrane electrodialysis. AP-0 salt… read more here.
