Abstract
Adsorption of trimethyl-substituted sulfonium, selenonium, and telluronium iodides on the armco-iron in 0.5 M H2SO4 is studied by the capacitance meth od. The compounds studied proved to be highly efficient inhibitors of the c athodic hydrogen evolution. The contribution of organic cations and anions to the total retardation of the cathodic process is evaluated. Some assumpt ions on the adsorption mechanism are proposed.
