Concept Introduction:
Column chromatography: Column chromatography is one of the methods used to isolate a single chemical compound from a mixture of compounds using solid phase like silica, alumina and liquid phase like hexane and ethyl acetate, etc.
Columns used for ion exchange are characterized by the presence of charged groups covalently attached to the stationary phase.
The attractive forces binding an anion to the column are related to the anion charge.
The attractive forces binding an anion to the column are related to the anion charge.
