Resumen: | En el presente trabajo de investigación se determinó la capacidad de remoción de cromo usando la microalga Scenedesmus dimorphus y la incidencia del fotobiorreactor de panel plano y del fotobiorreactor adaptado en el proceso, este último es un recipiente de vidrio cilíndrico, que cuenta con tres aberturas en la tapa, dos para la agitación y una para la desgasificación. A partir de la revisión bibliográfica de artículos que hayan realizado tratamiento de remoción de cromo con cultivos de microalgas, se definió un rango de concentración de cromo a escala laboratorio, mínimo y máximo encontrada, que corresponde a [1-300 mg/L], y por otra parte se determinó la forma química del cromo trabajada en dichos tratamientos, las cuales fueron Cr+3 y Cr+6. Para el desarrollo pre experimental, se tomaron 6 concentraciones de cromo dentro del rango establecido, 50mg/L, 100mg/L, 150 mg/L, 200mg/L, 250 mg/L, 300 mg/L y cada uno de los pre experimentos tuvo una concentración equivalente de las dos formas químicas del cromo, Cr+3 con óxido de cromo (Cr2O3) y Cr+6 con dicromato de potasio (K2Cr2O7), para así determinar el mejor resultado entre las concentraciones y entre las formas químicas del cromo. El crecimiento de la microalga Scenedesmus dimorphus es mayor en la concentración de 100 mg/L de cromo en la que se obtuvo una concentración celular (1,88E+06 cel/mL) y velocidad específica de crecimiento (0,215 d-1) para la muestra que contiene óxido de cromo (Cr2O3). |
Abstract: | In this research the capacity of chromium removal using the microalga was determined. Scenedesmus dimorphus and the incidence of the photo panel of the flat panel and of the photobioreactor adapted in the process, the latter is a cylindrical glass vessel, which has three openings in the lid, two for agitation and one for degassing. From the bibliographic review of articles that have carried out a chromium removal treatment with microalgae cultures, it is defined as a concentration range of a laboratory cycle, minimum and maximum found, which corresponds to [1-300 mg / L ], and on the other hand, the chemical form of chromium worked in said treatments was determined, which were Cr + 3 and Cr + 6. For the pre-experimental development, 6 chromium levels were taken within the established range, 50 mg / L , 100 mg / L, 150 mg / L, 200 mg / L, 250 mg / L, 300 mg / L and each of the pre had a concentration equivalent to the two forms of chromium, Cr + 3 with chromium oxide ( Cr2O3) and Cr + 6 with potassium dichromate (K2Cr2O7), in order to determine the best result between the concentrations and between the chemical forms of chromium. The growth of the microalga Scenedesmus dimorphus is greater in the concentration of 100 mg / L of chromium in which cellular was obtained (1.88E + 06 cel / mL) and specific growth rate (0.215 d-1) for the sample that It contains chromium oxide (Cr2O3). |
