Abstract

The adsorption of glycine on platinized platinum electrodes was studied in acidic medium (M HClO4) using radiotracer techniques. Under the experimental conditions studied the major part of the glycine is in the form of the +H2N-CH2-COOH cation. The potential dependence of the adsorption of glycine was found to be very similar to that of acetic and glycolic acids and anions. This experimental fact and the effect of anions and acetic acid on the adsorption of glycine seem to justify the previous assumption that the -COOH group plays a determining role in the anion-like adsorption behaviour of different derivatives of acetic acid and saturated aliphatic acids.
