A method for degradation of the perchlorate anion (ClO4
-) has been studied using
electrochemically generated zero-valent iron (ZVI) deposited on a porous carbon electrode. The
first strategy of this study is to produce the ZVI via the electrochemical reduction of iron (II)
on a porous carbon electrode coated with a conducting polymer, instead of employing expensive
NaBH4. The present method produced well distributed ZVI on conducting polymer (polypyrrole
thin film) and increased surface area. ZVI surface can be regenerated easily for
successive reduction. The second strategy is to apply a mild reducing condition (-0.3 V) to
enhance the efficiency of the degradation of perchlorate with ZVI without the evolution of
hydrogen. The electrochemically generated ZVI nanoparticles may offer an alternative means
for the complete destruction perchlorate without evolution of hydrogen in water with high efficiency
and at low cost.
