Abstract
The adsorption of sodium dodecyl sulfate (SDS) on alumina was studied by using the surfactant ion-selective electrode. The adsorbance could be calculated from the potential and concentration response characteristics of surfactant ion-selective electrode to get surfactant adsorption isotherm. Further experiment results show that the adsorbance was greatly influenced by pH of the solution. It is demonstrated that surfactant ion-selective electrode could be utilized to measure surfactant concentrations in solution after adsorption equilibrium without solid-liquid separation.
Kurzfassung
Die Adsorption von Natriumdodecylsulfat (SDS) auf Aluminiumoxid wurde mittels einer ionensensitiven Tensid-Elektrode untersucht. Das Adsorptionsvermögen kann durch das Ansprechverhalten von Potential und Konzentration der ionensensitiven Tensid-Elektrode berechnet werden, um die Adsorptionsisotherme der Tenside zu erhalten. Weitere experimentelle Ergebnisse ergeben, dass das Adsorptionsvermögen in hohem Maße durch den pH der Lösung beeinflusst wird. Es wird gezeigt, dass die ionensensitive Tensid-Elektrode zur Messung der Tensidkonzentration in Lösung nach dem Adsorptionsgleichgewicht ohne Fest-Flüssig-Trennung genutzt werden kann.
