Oxidación de cianuro en disolución acuosa mediante ozonización en presencia de carbón activado modificado
[EN] The aim of this study was to analyze the role of activated carbon on cyanide ozonation in aqueous phase. The results show that activated carbon previously treated with ammonia had a marked effect on the kinetics of cyanide removal. According to the results obtained by FTIR and XPS techniques, ammonia treatment increase the superficial concentration of carbonyl groups, which in the interaction with ozone could potentiate the generation of highly oxidizing radicals on the medium, justifying the results obtained.
