ABSTRACT
A study of adsorption of carbonate ions at the interface of ZnO/aqueous solution of NaClO4 is presented. The concentration range of carbonate ions was 1⋅10-6 to 1⋅10-3 M. The shape of adsorption of carbonate ions plot vs. pH is characteristic for anions adsorption onto metal oxides and is called the “adsorption envelope”. In order to prevent carbon dioxide access to solution, all measurements must have been taken in special chamber in nitrogen atmosphere.
