Article Preview

A kind of bamboo char with high specific surface area has been studied as the absorption material of the activated carbon electrodes, and the electrosorptive deionization ability of the as-obtained electrodes for elimination of metal ions in tap water has been examined under certain direct voltage. The effects of the distance between the elect rode plates, and the numbers of the electrode plates have been investigated in detail. The results show that the electrodes exhibit the optimal deionization ability over 2 cm of distance between the electrode plates and 4 couples of the elect rode plates. The reverse wash treatment indicates that the activated carbon electrodes can be cycle used. The efficiency order of the electrosorptive deionization of different metal ions on the activated carbon electrode has been summarized as follows: Pb2+>Cu2+>Cr3+>Cd2+.
