Electrochemical Recovery of Arsenic |
摘要 |
Contemplated devices and methods for arsenic recovery employ a two-step process in which an arsenite and arsenate-containing solution is first subjected to a non-electrochemical reduction that reduces arsenate and arsenite. The arsenate-depleted arsenite-containing solution is the subjected to electrochemical reduction at alkaline pH using a cathode with a high-surface carbon portion. Most preferably, the treated solution is then used as eluent for an adsorbent that removed arsenate and arsenite from a water supply.
