Abstract: The absorbent material tests including adsorb-discharge comprehensive performance, electrical conductivity, heat resistance, operation performances, and the pad flexible electrolytic decontamination parameter selection were studied. The changes in the current density and spacing effect on electrochemical parameters were studied. The results show that absorbent fiber of absorbing materials is the most suitable for pad flexible electrochemical decontamination; the changes of current density and electrode spacing have different influence on the corrosion rate, the utilization rate of electrolyte, continuous electrolysis time, and initiation voltage. The electrolytic parameters matching with absorbing material are that current density is not more than 0.3 A/cm², and electrode spacing is not more than 4mm.
