Resumen
Resumen. La industria camaronera es una fuente rica en biomasa que actualmente genera residuos que constituye una problemática desde el punto de vista ambiental. Sin embargo, la extracción de quitina y quitosano, representan una interesante forma de aprovechar este material para la formulación de matrices adsorbentes. La preparación de perlas (beads) de quitosano-hierro (III) como adsorbentes de arsénico, representa una estrategia innovadora para tratar fuentes de agua con concentraciones del metal por encima del valor máximo permitido (10 μg As/L) reportado en algunas regiones de Costa Rica.
Abstract. The shrimp industry is a rich source of biomass that currently generates waste that constitutes a problem from an environmental point of view. However, the extraction of chitin and chitosan represents an interesting way to take advantage of this material for the formulation of adsorbent matrices. The preparation of chitosan-iron (III) beads as arsenic adsorbents represents an innovative strategy to treat water sources with concentrations of the metal above the maximum allowed value (10 μg As/L) reported in some regions of Costa Rica.
