38.  Studies Regarding Copper Recovery from Residual Solution on Naturals Zeolites

Authors: Corina Orha, Maria Likarec (Bicanin), Rodica Pode, Georgeta Burtica


Abstract:

Chlorination is widely used to control viral contamination, high levels of chlorine promote the formation of organic compounds in water that may be hazardous to human health, an alternative method, copper ion treatment, is known to be effective against bacteria and algae. Some studies of natural zeolites have been made for their profitable use in waste treatment. The more recent use of copper ions to inactivate microorganisms is well documented. In addition to bacteria, copper ions also are effective in controlling viruses, algae and fungi in the part per billion (ppb) range. The paper relate the copper regarding from residual solutions, on natrium form zeolite. The regarding studies was done on solutions in different concentration between 55 and 500 mg Cu2+/dm3. The experimental reserch was realised in dynamic regime, and the zeolite doped with copper will be used for water disinfection.
