Abstract: A method for the electrochemical remediation of a metal species comprises flowing a contaminated solution comprising a metal species to be removed through an electrochemical cell that includes a working electrode and a counter electrode spaced apart from the working electrode. The working electrode comprises a conductive substrate or current collector with a polymeric coating thereon, where the polymeric coating comprises a semiconducting or redox-active polymer. A reducing potential is applied to the electrochemical cell, thereby inducing the metal species from the contaminated solution to deposit onto the working electrode. After depositing the metal species, a recovery solution is flowed through the electrochemical cell. An oxidizing potential is applied to the electrochemical cell, thereby stripping the metal species from the working electrode and recovering the metal species in the recovery solution.

Abstract: Various aspects described herein relate to electrochemical devices, e.g., for separation of one or more target organic or inorganic molecules (e.g., charged or neutral molecules) from solution, and methods of using the same. In particular embodiments, the electrochemical devices and methods described herein involve at least one redox-functionalized electrode, wherein the electrode comprises an immobilized redox-species that is selective toward a target molecule (e.g., charged molecule such as ion or netural molecule). The selectivity is based on a Faradaic/redox-activated chemical interaction (e.g., directional hydrogen binding) between the oxidized state of the redox species and a moiety of the target molecule (e.g., charged molecule such as ion or netural molecule).

Abstract: Aspects of the present disclosure relate to electrochemical reduction of tobacco-specific nitrosamines (TSNAs). According to certain methods described herein, a tobacco composition containing one or more TSNAs and nicotine is contacted with a solvent to form a tobacco mixture. In some embodiments, the tobacco mixture is introduced into an electrochemical device comprising an anode and a cathode. The tobacco mixture may, in some cases, form at least part of an initial electrolyte mixture that is in physical contact with at least a portion of the anode and at least a portion of the cathode. In some instances, an electrical potential is applied between the anode and the cathode, thereby reducing one or more TSNAs in the initial electrolyte mixture and producing a reduced electrolyte mixture. In certain cases, application of the electrical potential between the anode and the cathode does not cause non-TSNA components of the tobacco mixture (e.g.
