| Abstract: |
| The problems of single ion activity measurement by using the membrane
potential were discussed from the kinetic point of view.The K+ activity in pure KCI solution and the mixed solution with multiple ions were measured with a certain concentration by using K clay membrane electrode.The results obtained by which were identical
with those obtained from the calculation by Debye一Hii ckel limited equation.It is
proved that the K clay membrane potential really can reflect the response of simple ion
activity· |
| Key words: clay membrane electrode,membrane potential,kinetics,single ion activity |
