Activación de persulfato mediada por luz ultravioleta para la degradación de cianocomplejos de cobalto en aguas residuales de minería
Schnorr, Carlos Eduardo; Castilla-Acevedo, Samir (Corporación Universidad de la Costa, 2021-05-13)En este espacio propiciado por el Departamento de Ciencias Naturales y Exactas, se explica cómo se da la degradación de aguas residuales mineras provocadas por la activación de persulfato (PS)la cual se da por diferentes ... -
Data on the diagnosis of the management of the primary waste from electrical and electronic equipment in health care institutions in Barranquilla, Colombia
Gandara-Perez, Helen Marcela; Lubo-Hoyos, Nelson Enrique; Castilla-Acevedo, Samir; Fuentes Gandara, Fabio Armando (Corporación Universidad de la Costa, 2020-08-27)Economic and technological development advances exponentially, and the implementation of new technologies in the health sector has become a source of waste for electrical and electronic equipment (WEEE). Electrical and ... -
Dataset of the efficiency of the ultraviolet light activation of persulfate ion for the degradation of cobalt cyanocomplexes in synthetic mining wastewater
Castilla-Acevedo, Samir; Betancourt Buitrago, Luis Andrés; Machuca-Martínez, Fiderman; Machuca-Martínez, Fiderman (Data in Brief, 2020-02-28)In recent years, the extraction of gold has become important for the development of nations. However, mining wastewater represents an environmental problem due to its high content of free cyanide-based compounds and weak ... -
Degradation of hexacyanoferrate (III) ion by the coupling of the ultraviolet light and the activation of persulfate at basic pH
Ibargüen-López, Héctor; López-Balanta, Brian; Betancourt Buitrago, Luis Andrés; Serna-Galvis, Efraim A.; Torres-Palma, Ricardo A.; Machuca-Martinez, Fiderman; Castilla-Acevedo, Samir (Corporación Universidad de la Costa, 2021)The ultraviolet light activation of persulfate (PS) under alkaline conditions was evaluated for treating hexacyanoferrate (III) ion ([Fe(CN)6]3-). The effect of the wavelength type (i.e., UVA and UVC), initial PS concentration ... -
Enhancement of the adsorption of hexacyanoferrate (III) ion on granular activated carbon by the addition of cations: a promissory application to mining wastewater treatment
González-Ipia, Nicolás; Bolaños-Chamorro, Kevin Camilo; Acuña-Bedoya, Jawer David; Machuca-Martínez, Fiderman; Castilla-Acevedo, Samir (Corporación Universidad de la Costa, 2020-07-27)The influence of the addition of cations on the adsorption of [Fe(CN)6] 3− on granular activated carbon (GAC) was evaluated. The tests were performed at three pH values (3, 8.2, and 13) to determine the repulsion or ... -
Photocatalytic degradation of cobalt cyanocomplexes in a novel LED photoreactor using TiO2 supported on borosilicate sheets: A new perspective for mining wastewater treatment
Joven-Quintero, Sergio Andrés; Betancourt Buitrago, Luis Andrés; Castilla-Acevedo, Samir; Acosta-Herazo, Raúl; Machuca-Martinez, Fiderman (Universidad de la Costa, 2020)The photocatalytic degradation of hexacyanocobaltate ion ([Co(CN)6]3−) by TiO2 supported on borosilicate sheets was studied in a novel photoreactor operated under UVA-LEDs irradiation. The presence and absence of O2 during ... -
Ultraviolet light-mediated activation of persulfate for the degradation of cobalt cyanocomplexes
Castilla-Acevedo, Samir; Betancourt Buitrago, Luis Andrés; Demetriou Dionysiou, Dionysios; Machuca-Martínez, Fiderman (Universidad de la Costa, 2020-03-06)The ultraviolet light activation of persulfate (PS) was evaluated for the degradation of cobalt cyanocomplexes, which are considered as some of the most recalcitrant compounds present in mining wastewater. The influence ...
