Elektrochemiczne oczyszczanie ścieków za pomocą porowatych elektrod węglowych

Birch activated coal fixed between titanium and ruthenic oxide electrodes was used. The experiments were carried out with a model solution containg 3000 mg/dm3 natrium ions and 5.44 mg/dm3 copper (II) ions. It was shown that adsorption ofnatrium ions was observed only at imposing voltage. The adsorption of copper (II) ions was worse, since the adsorption process had a competitive character. Interrelation between voltage, submitted on electrodes of a cell (2 - 35 V) and quantity of desorbed ions was established. Efficiency of the adsorption and desorption processes of naturium and copper ions amounted accordingly after 7 hours: 51.17%, 73.53%. and 46.63%, 20.83%.
