Abstract
La contaminación del agua por antibióticos es un serio problema ambiental. El mal manejo de los medicamentos no utilizados y la descarga a través de los residuos corporales aumentan este problema, especialmente porque la mayoría de las plantas de tratamiento de aguas residuales y los sistemas sépticos no fueron diseñados para tratar este tipo de contaminantes. En diversos estudios, los científicos han reportado en aguas residuales las principales categorías de contaminantes como son los contaminantes orgánicos persistentes (POPs), pesticidas, productos farmacéuticos y de cuidado personal (PPCPs). Los PPCP son contaminantes emergentes que representan una gran preocupación, estos se encuentran las aguas superficiales y potable. Esta investigación se basa en la remoción de dos antibióticos en agua utilizando la planta Leucaena Leucocephala como una alternativa para remediar los cuerpos de agua y suelo de contaminantes. Los antibióticos en estudio son del grupo de la fluoroquinolona y son ampliamente utilizado para tratar infecciones. La determinación de Ciprofloxacina y Levofloxacina en los extractos de L. Leucocephala se realizó mediante las técinas de cromatografía líquida de alta resolución de fase inversa y voltametría cíclica. Los resultados de esta investigación demuestran que los contaminantes están siendo absorbidos por la planta L. Leucocephala. Se encontró que en toda la planta se acumuló un 15.8% de Ciprofloxacina y un 26.6% de Levofloxacina.
Water contamination due to antibiotics is a serious environmental problem. Flushing of unused medications and discharge through body waste increase this problem, especially since most of sewage treatment plants and septic systems were not designed to deal with such contaminants. In several studies, scientists have reported presence of major pollutants like persistent organic pollutants (POPs), pesticides, pharmaceuticals and personal care products (PPCPs). PPCPs represent pollutants of emerging concern, these contaminants are in surface water and drinking water. This research is intended to remove two antibiotics by Leucaena Leucocephala plant as an alternative to remediate water contaminated with antibiotics. The antibiotics studied in this research belong to the group of fluoroquinolones and are widely used for infections. Ciprofloxacin and Levofloxacin determinantion in L. Lecucocephala extract was made by reversed-phase high-performance liquid chromatography and cyclic voltammetry. Results show that contaminants are entering in the L. Leucocephala plant. It was found that was accumulated a 15.8% for Ciprofloxacin and 26.6% for Levofloxacin in the plant.
