Some methods that have been developed to regenerate spent sulfolane include vacuum and steam distillation, back extraction, adsorption, and anion-cation exchange resin columns.
32.
Actinium can then be separated from radium, with a ratio of about 100, using a low cross-linking cation exchange resin and nitric acid as eluant.
33.
It is then treated with high-pressure elution from cation exchange resins, and the berkelium phase is oxidized and extracted using one of the procedures described above.
34.
It should be noted that soil properties, such as organic carbon content and cation exchange capacity had significant impacts of the adsorption coefficients reported in the table below.
35.
Previous procedures to isolate phosphorylated proteins included radioactive labeling with 32 P-labeled IMAC ), strong cation exchange ( SCX ) chromatography, or titanium dioxide chromatography.
36.
The conductivity of cation exchange effluent is always quite high due to the presence of anions and hydrogen ion and therefore conductivity measurement is not useful for this purpose.
37.
If the renal cation exchange system is interfered with ( as with the medications listed above ), a larger percentage of dofetilide is cleared via the CYP3A4 isoenzyme system.
38.
In the case of a water softener, the cation exchange resin is exchanging sodium ( the Na ion of NaCl ) for hardness minerals such as calcium and magnesium.
39.
Cation exchange chromatography resolved four lethal peaks from " N . a . annulata " venom and six lethal peaks from " N . christyi " venom.
40.
Framework Substitution with W-band ENDOR has been used to provide experimental evidence that a metal ion is located in the tetrahedral framework and not in a cation exchange position.
