Abstract
La investigación tuvo como objetivo determinar la capacidad fitorremediadora de la especie Hydrocotyle ranunculoides L. f. en aguas contaminadas por metales pesados (Cu, Mn y Al) de la quebrada Pacchantay. Se realizó un muestreo puntual de agua contaminada de la quebrada en un recipiente de 20L. La especie fue recolectada en Bancapata y luego cultivada en un sistema hidropónico con 50L de agua purificada. Durante un mes, las plantas se alimentaron semanalmente con soluciones A y B. Luego, se añadieron 5L de agua de río contaminada con metales pesados (Cu, Mn y Al) a tres grupos, mientras que al grupo control se le dio solo agua purificada. Posteriormente, se agregaron 20 unidades de la especie Hydrocotyle Ranunculoides L.f. a cada una de las cubetas, y se llevó a cabo la fitorremediación durante un mes. En este periodo, se midieron los parámetros fisicoquímicos (conductividad, pH, temperatura) y la concentración de metales pesados (Cu, Mn y Al) en agua y plantas fueron analizados antes y después del proceso de fitorremediación por el método espectroscopía de Absorción Atómica. Los resultados muestran que al analizar las comparaciones múltiples de cobre antes y después del tratamiento en agua, se observa diferencias significativas. Después del tratamiento, los metales aumentaron significativamente tanto en hoja, raíz y tallo. Se concluye que Hydrocotyle ranunculoides L. f tiene capacidad fitorremediadora para los metales Cu (98.97%) > Mn (73.01%) > Al (59.40%) y disminución de acidez en el agua.
The objective of the research was to determine the phytoremediation capacity of the species Hydrocotyle ranunculoides L. f. in waters contaminated by heavy metals (Cu, Mn and Al) from the Pacchantay stream. Spot sampling of contaminated water from the stream was carried out in a 20-liter container. The species was collected in Bancapata and then grown in a hydroponic system with 50L of purified water. For a month, the plants were fed weekly with solutions A and B. Then, three groups were added 5 liters of river water contaminated with heavy metals (Cu, Mn and Al), while the control group He was given only purified water. Subsequently, 20 units of the species Hydrocotyle Ranunculoides L.f. were added. to each of the buckets, and phytoremediation was carried out for one month. In this period, the physicochemical parameters (conductivity, pH, temperature) and the concentration of heavy metals (Cu, Mn and Al) in water and plants were analyzed before and after the phytoremediation process using the Atomic Absorption spectroscopy method. The results show that when analyzing multiple comparisons of copper before and after treatment in water, significant differences are observed. After treatment, metals increased significantly in both leaf, root and stem. It is concluded that Hydrocotyle ranunculoides L. f has phytoremediation capacity for the metals Cu (98.97%) > Mn (73.01%) > Al (59.40%) and a decrease in acidity in the water.
