... and 0.1 M 2 (open markers) in FS-13 solvent. Aqueous phases contain 0.001 M Eu(NO3)3 and 0.010 M HNO3. The solid lines depict slopes of m = 0 and m = -2,. HNO3 compared to only 1 M HNO3 (no stripping when. Aliquat 336 was not added). The effect of Alamine 336 addition was also investigated for SHLW at 1 M HNO3 ... To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above. ... M Ligand 1 in 0.25 M HNO3 and 0.15 M Ligand 2 in 0.25 M. HNO3) were shaken for different times from 5 to 60 minutes. The stripping kinetics proved to be fast ... M HNO3 system: (1) 7 M HNO3; (2) 5 M HNO3; (3) 3 M HNO3; (4) 1 M HNO3; (5) 0.5 M HNO3; (6) 0.1 M HNO3. By using the best anion exchangers in a given system ... Milliequivalents of HNO3 = 25 × 0.15 = 3.75 Milliequivalents of LiOH = 40 × 0.25 = 10 Therefore, the solution is basic. water, then 8 M HNO3. Once all of the acid has drained, add approximately 1 cm depth of glass beads on top of the resin. 6.3.4.
