Chitin, chitosan recovered from fly crabs shells have been investigated by the elemental analysis, potentiometric titraton and FT–IR spectrometry methods. The molecular weght of chitosan was determined by measuring their viscosity. The adsorption kinetics of reactive dye and equilibrium conditions has been investigated. The adsorption of reactive dye on chitin and chitosan proceeds according to pseudo – second – order kinetic equation. Adsorption investigations under equilibrium conditions showed that. Theses results were fitted by both Langmuir and Freudlich models.
