description The contamination of receiving water bodies by heavy metals due to anthropomorphic activities is of great significance to human health. There are metals that have a high capacity to form radicals that alter cellular functions when they exceed certain concentrations, for example, a prolonged exposure to concentrations greater than 20 mg of copper/L promotes the development of cancer. The invention relates to a thermoplastic matrix of chitosan (Ch) and polycaprolactone (PCL) for the removal of heavy metals in waste water, which, used in a ratio of 2:1 p/p respectively, offers a capacity of 62.5 mg Cu2+/g adsorbent (ads) in continuous processes with a HRT of less than 2 hours, and which permits various reuse cycles. La contaminación de los cuerpos receptores de aguas por metales pesados debida a actividades antropomórficas es de gran importancia para la salud humana. Existen metales que poseen una alta capacidad de formar radicales alterando las funciones celulares cuando se exceden ciertas concentraciones, por ejemplo, una exposición prolongada a concentraciones por arriba de 20 mg de cobre/L favorece el desarrollo de cáncer. La presente invención se refiere a una matriz termoplástica de quitosano (Ch) y poli-e-caprolactona (PCL) para la remoción de metales pesados en aguas residuales que utilizados en una relación 2:1 p/p; respectivamente, ofrece una capacidad de 62.5 mg Cu2+/g adsorbente (ads) en procesos continuos con un TRH menor a 2 horas, y que permite varios ciclos de reutilización.
