Decolorization of Reactive Black 5 Dye by Heterogeneous Photocatalysis with TiO2/UV
Reactive Black 5 (RB5) is an azo dye widely used in the textile industry because of its high chemical stability. Since it does not entirely fix on the fabrics, it pollutes water sources. In this work, the decolorization ...Universidad Nacional de Colombia Revistas electrónicas UN Revista Colombiana de Química. 2018-05-01 -
EVALUACIÓN DE LA ACTIVIDAD ANTIOXIDANTE DE ACEITES ESENCIALES EN EMULSIONES DEGRADADAS POR RADIACIÓN ULTRAVIOLETA
