| 20080223730 | ELECTROCHEMICAL TREATMENT OF SOLUTIONS CONTAINING HEXAVALENT CHROMIUM - There is disclosed a process of electrochemical reduction, optionally coupled to a final stage of chemical finishing, of solutions containing hexavalent chromium. The electrochemical reduction is carried out making use of a cell of cylindrical geometry with tangential solution inlet and outlet, which establishes and maintains a spiral flow across the whole electrolysis bulk, achieving effective mass transport conditions. | 09-18-2008 |
