Аннотация:The adsorption behavior of 2,2,6,6-tetramethyl-4-oxypiperidine is studied on mercury in alkaline solutions of sodium tripolyphosphate in the absence and presence of a constant amount of aminoacetic acid. A dependence of the adsorption energy of the studied substance on the electrode potential is calculated from experimental isotherms of two-dimensional pressure. On the basis of this dependence, it is concluded that two adsorption states are realized at the adsorption of this substance on a mercury surface. It is shown that the surface activity of 2,2,6,6-tetramethyl-4-oxypiperidine decreases in the presence of aminoacetic acid. The adsorption parameters are calculated.
