摘要：

A method is proposed for the estimation of maximum surface concentrations of adsorbates by ac impedance measurements at low electrode coverages. This gives better results than methods based on measurement of the time for full electrode coverage. The dyestuff erythrosin is examined and found to have a maximum surface concentration on mercury of 1·43 × 10-10 mole/cm2, or an area requirement of 117 Å2/molecule. This allows some conclusions about the orientation of the molecule on the mercury surface. © 1968.
