“…These viscosities a r e not excessively xigh for column operation since 1.5M aluminum nitrate (about 3.3 centipoises) is used a s aqueousfeedfor solvent extraction in pulsed columns, and 2M aluminum nitrate (6.2 centipoises) is used a s scrub inpacked columns at ICPP. 1.25 Further Data. Additional stability, electrical conducti.vity, density, and viscosity data have been obtained for the m o r e general system in which the concentration of the different metal ions was varied independently.…”
