Agua Subterránea, BTEX, Toxicidad, Adsorción, Ceniza de Cáscara de Arroz, Allium CepaResumen
Este estudio investigó la eliminación de compuestos BTEX del agua mediante un equipo compacto que consta de succión al vacío, aireación y un sistema de adsorción con 50 % de carbón activado y 50 % de ceniza de cáscara de arroz. La concentración de BTEX se determinó por cromatografía de gases. Se realizaron pruebas de ecotoxicidad para evaluar la longitud de la raíz de Allium cepa, considerando la muestra cruda al 100 % (BTEX100) y diluciones al 50 % (BTEX50) y al 25 % (BTEX25). Se llevaron a cabo tres pruebas con una duración total de 240 minutos, con muestreo a los 0 minutos (T0), 120 minutos (T120) y 240 minutos (T240). Los resultados mostraron eficiencias de eliminación superiores al 99 % de las concentraciones de los compuestos BTEX estudiados, lo cual se asocia principalmente al proceso de succión al vacío. Sin embargo, las pruebas de ecotoxicidad indicaron la necesidad de incluir una etapa de adsorción en el proceso de tratamiento, con el fin de reducir la toxicidad del agua tratada.
