The adsorption behavior of polyvinylpyrrolidone (PVP), polyethyleneglycol (PEG), and alkylphenoxy polyethoxy ethanols (Triton X) on a smooth platinum electrode was investigated by observation of the inhibition effect on the electrosorption of hydrogen and oxygen in the potential range between hydrogen and oxygen evolution. The adsorption of PVP, PEG, and Triton X on platinum always took place within the potential range from −0.20 to 1.25 V <I>vs.</I> SCE, the inhibition effect on the electrosorption of hydrogen and oxygen being distinctly shown. The order of inhibition of these adsorbates was Triton X>PVP>PEG. The inhibition effect became larger in most cases with decreasing mean molecular weight of adsorbate. In contrast to the case with a mercury, the adsorbates were oxidized or reduced on the platinum electrode in the adsorption range, the anodic peak due to oxidation being distinctly revealed in the case of PEG.
