Аннотация:
The mutual effect of thallium and phenol adsorption in the Hg, Tl, Tl+, H2O system at 2.0 M phenol concentration has been studied. It has been shown that phenol and thallium adsorption suppress each other in a wide potential range with the result that at the potential of maximum total thallium adsorption (ΓTl + ΓTl-) phenol adsorption drops nearly to zero. However, at the most negative potentials the mutual suppression changes to mutual increase of adsorption. The picture of the structure of the mercury surface layer in the presence of thallium and NO3- ions, developed in the previous communication, allows a qualitative explanation of the effects observed. The results of ref. 3 obtained without taking into consideration the changes in Tl concentration in amalgam caused by its oxidation by atmospheric oxygen have been partly corrected. © 1974.
