Reversed-phase extraction chromatography of Germanium(IV) with tributyl phosphate on silica gel.
Germanium(IV) can be separated by reversed-phase extraction chromatography with TBP as stationary phase on a column of silica gel, with 6M hydrochloric acid as the mobile phase, and stripped with various eluents. Germanium can thus be separated (by selective extraction) from those elements which are not extractable with TBP, and (by selective stripping) from elements that are extractable.
