Equilibria effects in the dynamic ion-exchange separation of metal ions

摘要: Equilibria occurring during the dynamic ion exchange separation of metal ions were examined, and their effect on chromatography was evaluated. Bonded reversed-phase silica, pure organic reversed phase, silica columns used to differentiate between role reverse phase. The results show that system peaks had most important influence applicability exchangers quantitative determinations. response sample composition (pH, ionic strength, matrix effects) complicated could not be predicted easily. effects can cause analytical errors identified recommendations for elimination such are given.
