Removing dissolved oxygen from water

In a process for the removal of oxygen dissolved in water for corrosion prevention and based on hydrazine, the activators used comprise cationic and/or anionic complexes of trivalent cobalt with inorganic ligands or mixtures thereof. Among the preferred activators are (Co(NH3)5Cl)Cl2 and Na3Co(NO2)6...
