Quantitative Bestimmung von Phosphonaten in Waschmitteln
The selective determination of phosphonates in detergents with ion chromatography is disturbed by the presence of Al or other metal ions. Due to the formation of stable metal-phosphonate complexes, phosphonate is linked and thus a determination is not possible. The disturbance caused by AlIII can be...

| Zusammenfassung: | The selective determination of phosphonates in detergents with ion chromatography is disturbed by the presence of Al or other metal ions. Due to the formation of stable metal-phosphonate complexes, phosphonate is linked and thus a determination is not possible. The disturbance caused by AlIII can be eliminated by adding a competing agent to the analyte solution. |
