Optimización de biocarbón a partir de residuos de camarón para la adsorción de arsénico en aguas contaminadas.

Abstract

Water contamination due to the heavy metal (As) is a major ecological and health issue. This study analyzed the production and optimization of biochar from shrimp waste as an option for As adsorption in contaminated waters. The biochar was obtained through a pyrolysis process at 600°C and was activated with (HCl) to enhance its adsorption capacity. Adsorption experiments were conducted using different biochar concentrations, specifically 4g and 6g, resulting in a reduction of As in water, although it did not exceed the maximum permissible limits according to Ecuadorian regulations. Nevertheless, the biochar demonstrated potential as a material capable of adsorbing substances; therefore, future improvements could increase its efficiency. This study contributes to the sustainable management of waste produced by the shrimp industry and promotes the growth of a circular economy.
