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 ... -
Effect of the presence of inorganic ions and operational parameters on free cyanide degradation by ultraviolet C activation of persulfate in synthetic mining wastewater
Satizabal-Gómez, Valentina; Collazos-Botero, Manuel Alejandro; Serna-Galvis, Efraím A.; Torres-Palma, Ricardo A.; Bravo-Suárez, Juan J.; Machuca-Martínez, Fiderman; Castilla-Acevedo, Samir Fernando (2021)This work studied the influence of several parameters on free cyanide (CN−) degradation (50 mg L−1) by the UVC-activated persulfate (PS) at alkaline conditions (UVC/PS). Firstly, photolysis and alkaline activation of PS ... -
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 ... -
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 ...
