Ing. Aime Joselyn Garcia Lugo, curse la carrera de Ingeniero químico metalurgista y materiales, en la Facultad de Metalurgia en el ciclo escolar del 2017 al 2022.

Fungí como ayudante de investigador en la universidad. Lleve a cabo mi servicio social dentro de la Facultad de Metalurgia brindando asesorías de la materia de química a los estudiantes durante las horas requeridas por el plan de estudios.

Concluí el plan de estudios de la carrera con acentuación en metalurgia extractiva llevando materias practicas con valor curricular en los diferentes laboratorios de la institución, al mismo tiempo trabajé en el área de síntesis de materiales en la cual finalicé el proyecto de investigación titulado “Síntesis y caracterización de biocarbones a partir de residuos de maíz para la remoción de azul de metileno” mediante el cual se me permitió titularme (modalidad tesis). 

Actualmente me encuentro como docente de asignatura en la institución de educación media superior Bachilleres Frontera, en donde soy la encargada de impartir clases/asesorías de las materias de Química I y II según el plan de estudios de la preparatoria.


Water pollution is an issue of current concern worldwide since it is the primary liquid for the proper development of all living beings.

Since there are several sources of contamination, different techniques have been used to remove contaminants. The most efficient technique so far is adsorption, allowing the use of different materials to carry it out.

In this work, the use of biochar modified superficially with magnetic particles by chemical coprecipitation, obtained from corn residues from the ejido 8 de Enero, was investigated to remove methylene blue from aqueous effluents at different concentrations.

Optimal operating conditions were studied to elaborate the materials, as well as the properties, zero loading point, isotherms and adsorption kinetics; being the magnetically modified biochar (BCFe) the one that presented the best behavior at different concentrations (1 and 10 ppm).

The experimental isotherms were adjusted with the Langmuir model, while the adsorption kinetics were adjusted with the pseudo-second order model.

An adsorption capacity of 4.85 mg/g and 4.30 mg/g at 10 ppm was obtained, while a removal of 96.89% and 50.62% at 1 ppm concentrations and 75.94% and 53.37% at 10 ppm concentrations were achieved by the magnetically modified biochar (BCFe) and unmodified biochar (BC), respectively. 

Both biochars may be promising materials for efficient removal of organic pollutants from aqueous effluents.
