Abstract
Esta investigación tuvo el objetivo de demostrar la influencia de la microalga Chlorella en
la remoción de Imidacloprid y la influencia de este contaminante en el porcentaje final de
imidacloprid removido de cada tratamiento. Además la intensidad luminosa y el tiempo
influyen en dicho proceso.
La máxima remión de Imidacloprid fue de 97.7% en el día 45 y se obtuvo en el tratamiento
que tenía 10ppm de concentración inicial de Imidacloprid con la dosis de 100 ml de Chlorella
por cada litro de agua contaminada bajo influencia de luz natural. Este tratamiento se repitió
bajo la influencia de fotoperiodos de 24 horas e intensidades luminosas de 2000, 4000 y
6000 lux, donde el máximo porcentaje de remoción fue de 67.56% al día 38 bajo efecto de
4000 lux.
A medida que aumenta la población de Chlorella sp. aumenta el porcentaje de remoción,
pero a mayor concentración inicial de imidaclopri la remoción es menos eficiente porque el
contaminate tiene efecto tóxicos sobre las micoalgas. Por otro lado, la fotoinhibición de
Chlorella por un fotoperioror prolongado también perjudica a la remoción de imidacloprid.
This research aimed to demonstrate the influence of the microalgae Chlorella on the removal of Imidacloprid and the influence of this contaminant on the final percentage of imidacloprid removed from each treatment. In addition, light intensity and time influence this process. The maximum remission of Imidacloprid was 97.7% on day 45 and was obtained in the treatment that had 10ppm of initial concentration of Imidacloprid with the dose of 100 ml of Chlorella per liter of contaminated water under the influence of natural light. This treatment was repeated under the influence of 24-hour photoperiods and luminous intensities of 2000, 4000 and 6000 lux, where the maximum percentage of removal was 67.56% per day 38 under the effect of 4000 lux. As the population of Chlorella sp. increases the percentage of removal, but the higher the initial imidaclopri concentration the removal is less efficient because the contaminate has toxic effect on the mycoalgas. On the other hand, the photoinhibition of Chlorella by a prolonged photoperioror also impairs the removal of imidacloprid.
