processo de restauração de membrana, membrana restaurada e método para proteger um catodo de uma célula da corrosão

摘要

Embodiments include membrane restoration process. A membrane can be restored by replacing an anolyte and a catholyte of a cell with a solution having an organic acid. The cell can include an anode, a cathode and a membrane fouled with a metal. A cheleate can be formed with the metal and the organic acid of the solution and an electric current can be provided between the anode and the cathode of the cell to protect the cell from corrosion while forming the chelate.
