| 1 | EFFECT OF SnO_2 ADDITION ON THE SERVICE LIFE AND ELECTROCHEMICAL PROPERTIES OF Ti/IrO_2,+Ta_2O_5 ANODES IN PHENOLSULFONIC ACID SOLUTION显示文摘Service life of two different oxide anodes in phenolsulfonic acid (PSA) solution was investigated by accelerated electrolysis. The durability of Ti/IrO2+Ta2 O5 anode increased by the addition of SnO2 in the mixed oxides. The degradation mechanisms of Ti/IrO2+ Ta2 O5 and Ti/IrO2 +Ta2 O5 +SnO+2 anodes were different. It was shown from the observation of scanning electron microscopy (SEM) and the electrochcmical measurement that, the deactivation of Ti/IrO2 + Ta2 O5 anode was due to the build-up of an organic film on surface. The growth of the covered film on surface was restricted by addition of SnO2, which resulted in increasing of the service life of anodes. The over-potential for oxygen evolution on Ti/IrO2 +Ta2 O5 electrode increased after doping SnO2, and the intermediate products of PSA building-up on the surface was much more rapidly oxidized. Meanwhile, a certain part of the surface oxide deposit entered into the solution leading to loss of oxides, which resulted in degradation of Ti/IroO2 + Ta2 O5 anode containing SnO2 component. | J.M.

| 2 | EIS STUDY ON ZINC RICH PAINTS IN 3.5% NaCl SOLUTION BY DOUBLE-CELL TEST显示文摘This paper discussed the possibility of obtaining electrochemical impedance spec-troscopy (EIS) responses of zinc rich paints (ZRP) using serial double-cell (SDC). The influence of counter electrode was outlined. An equivalent circuit (EC) for the double-cell was then discussed. The relationship between EC, the time constant, the parameters in EC of SDC and those of two single cells was also discussed. The results gained by serial double cell test are consistent with those of single cell test. It can be concluded that double cell test method can be used to study ZRP completely. | DM. Xie, J.M.
