Efficiency of the removal of microcystin-LR byUV-radiation and hydrogen peroxide
ABSTRACT : Due to the harmful effects associated with the presence of microcystin-LR (MC-LR) cyanotoxin, photo-degradation assays were performed in natural and distilled water using the combined action of ultraviolet (UV) radiation and hydrogen peroxide (H2O2). The effect of H2O2 content and UV irra...

ABSTRACT : Due to the harmful effects associated with the presence of microcystin-LR (MC-LR) cyanotoxin, photo-degradation assays were performed in natural and distilled water using the combined action of ultraviolet (UV) radiation and hydrogen peroxide (H2O2). The effect of H2O2 content and UV irradiance was evaluated and optimized using a multilevel factorial design in distilled water spiked with 20 µg L-1 MC-LR. The coupled UV/H2O2 system under optimal operating conditions (0.63 mW cm-2 irradiance and 30 mg L-1 H2O2) was more effective than the individual action of UV irradiance or H2O2 content for 30 min of treatment time, since a reduction of 97.78% of MC-LR was achieved. After optimizing the operating conditions, they were applied for natural water, obtaining MC-LR removals similar to those achieved with distilled water (99.59 and 99.73%, respectively), reaching a final MC-LR concentration in both matrices well below the maximum recommended limit established by WHO for MC-LR in drinking water, fixed at 1 µg L-1. 15 mg L-1 of H2O2 were also tested, and although 98.08% of MC-LR elimination was found for a reaction time of 60 min, WHO advisable limit was not surpassed. The UV/H2O2 process could be considered as an alternative to the conventional processes water facilities are operating with to tackle the problem of fresh water pollution with cyanotoxins, providing the accomplishment of the whole set of water quality standards included in the legislation. |

El efecto del contenido de H2O2 y la irradiación UV se evaluó y optimizó utilizando un diseño factorial multinivel en agua destilada enriquecida con 20 µg de L-1 MC-LR. El sistema acoplado UV/H2O2 en condiciones óptimas (0.63 mW cm-2 de irradiación y 30 mg de L-1 H2O2) fue más efectivo que su acción individual durante 30 min de tratamiento, ya que se logró una reducción del 97.78% de MC-LR. Después de optimizar las condiciones de operación, se aplicaron para agua natural, obteniendo remociones de MC-LR similares a las obtenidas con agua destilada (99.59 y 99.73%, respectivamente), alcanzando una concentración final de MC-LR en ambas matrices muy por debajo del límite máximo recomendado por la OMS para MC-LR en agua potable, fijado en 1 µg L-1. También se probó 15 mg L-1 de H2O2, y aunque se encontró un 98.08% de eliminación de MC-LR durante 60 min, el límite aconsejable de la OMS no se superó. El proceso UV/H2O2 podría considerarse una alternativa a los procesos convencionales de potabilización para abordar el problema de la contaminación del agua dulce con cianotoxinas, proporcionando el cumplimiento de los estándares de calidad del agua legislados.COL004040211application/pdfengUniversidad de Antioquia, Facultad de IngenieríaMedellín, Colombiahttps://creativecommons.org/licenses/by-nc-sa/4.0/http://creativecommons.org/licenses/by-nc-sa/2.5/co/info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Efficiency of the removal of microcystin-LR byUV-radiation and hydrogen peroxideEficiencia en la remoción de Microcistina-LR empleando radiación ultravioleta y peróxido de hidrógenoArtículo de investigaciónhttp://purl.org/coar/resource_type/c_2df8fbb1https://purl.org/redcol/resource_type/ARThttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPolución del aguaWater pollutionToxinasToxinsTratamiento del aguaWater treatmentProcesos de oxidación avanzadahttp://aims.fao.org/aos/agrovoc/c_8321http://aims.fao.org/aos/agrovoc/c_7828http://aims.fao.org/aos/agrovoc/c_ef195799Rev.
