摘要: The behavior of cyanide concentration in a wastewater galvanized process metalic recover industry was studied. photodegradation with Artificial UV light, titanium oxide (TiO2) as catalyst and hydrogen peroxide used to degrade this waste water (400 ppm CN-). determined electrode ion-selective method. In study annular shaped reactor concentric tubes laboratory scale. It obtained reduction 65.5% two hours recirculation time. Kinetic models just Langmuir-Hinshelwood. Experiments four time reinyection made. 97.37 % concentration. addition oxygen didn´t improved the reduction. performed cyanide.
