Authors : Carlos Vidal-Tovar, Carlos, Rafael Correa-Turizo, Carlos Severiche-Sierra and Wilman Cabrera-Lafaurie

Abstract: Among the persistent chemical compounds in the residual discharges are the highly toxic cyanides used in the industrial sector and in particular the mining industry for the extraction of gold, frequently appearing in low concentrations in the water, deteriorating its quality. Being of vital importance the treatment of the cyanide effluent, to reduce the concentration of cyanide before its final discharge, thus producing less toxic effluents, to achieve this several studies have been carried out and developed methods for its treatment, chemical, physical and biological An alternative to improve the quality of wastewater is the heterogeneous photocatalysis mediated by different semiconductors such as TiO , considering this a simple technology and 2 economical in relation to bioremediation treatments, effective and innovative in our environment for aqueous effluents.
