摘要：
The sorption of sulfuric and hydrochloric acid anions in polyaniline has been studied by the radioactive tracer method. It is shown that the extent of sorption is a function of the potential of the electrode on which polyaniline is deposited, the direction of potential shift and the solution pH. It has been established that the detachment of one electron from polyaniline upon doping is accompanied by incorporation of the HSO-4 anion polymer. Irreversible degradation of polyaniline leads to decrease of the anion sorption component caused by doping. © 1990.
