Membrane separation in the calculation and application mobility
Group mobility of rare earth elements in a geometric mean of c1) = Σqn iv = Σ (13) Σ 【'a ΣqlSΣ eggs. = And a (14) ΣqI-5 Similarly,air jordans, other groups can be calculated. Migration of only top components (such as Sm ~ Y) were calculated with points to get the product partition migration. The purity of fraction stays (such as the external water phase of heavy rare-earth after the migration to the inner water phase, the external phase purity of light rare earth) is calculated,air jordan shoes cheap, simply move the formula to calculate the rate of exchange rate can remain where : stay Rate roar. A 100% of a cI] \. The known product purity requirements, according to the original partition, and a rare earth migration rate and migration rate of data generation stays formula to calculate the first,ugg milano, second, third, and all other products for distribution after the migration (purity), choose to to achieve product purity (> 95) requires the series \(12) (14) Calculate the known (see Table 2), light rare earth by the three migration, secondary migration by heavy rare earth, and their purity were 97.O and 95.3} 98.1 experimental results are followed and 98.3, consistent with the results. to determine the migration of light rare earth series should be three, the migration of heavy rare earth series should be = level.
