Publicación Acceso abierto Determinación de precursores de dioxinas y furanos de los gases procedentes de un incinerador en un reactor fotocatalítico(2014-05-07) Ocampo, Aquiles; Giraldo-Orozco, J. M. (Jorge Mario)A chromatografic method for the determination of dioxins and furans from one of their precursors is shown from standards of measurements and from real samples of gases taken from an incineration plant in Itagüí, Colombia. This technique makes possible to do studies to obtain fair approximation of the dioxins and furans contained before doing determinations in high resolution equipments. Besides the photocatalytic technology is used as a method to get the elimination of dioxins and furans precursors from gases emitted by an incinerator, lowering the amount of reactive required in the depuration process.Publicación Acceso abierto Uso de lodos provenientes de la industria papelera en la elaboración de paneles prefabricados para la construcción(2014-05-08) Quinchía-Figueroa, A. M. (Adriana María); Valencia-García, M. F. (Marco Fidel); Giraldo-Orozco, J. M. (Jorge Mario)This work was based on the fabrication of drywalls as nonstructural elements for the construction industry, from the beneficial of the residual sludge from the treatment of waters served as the paper industry. The optimal mixtures, the suitable materials, and the stages of the process of fabrication of the panels to develop pieces were defined that fulfill the standards of resistance required and the technical norms associated to this kind of products. In this form not only new options of materials in the region are offered, but also offers an enormous environmental benefit from the assessment of an industrial waste assessment generated in great quantities.
