Abstract

In this study it was evaluated the use of magnetic chitosan beads in removal of textile and food azo dyes (Allura Red) taking into account some factors such as pH, the concentration of the dye and the mass of beads. To obtain the beads it was used chitosan 2 %, glutaraldehyde and magnetite (previously synthetized by hydrolysis oxidative), after that the beads and magnetite were characterized by infrared spectroscopy and scanning electron microscopy.
