In this work, the effect of cross-linking of chitosan beads on the removal efficiency of dye RB 5 from aqueous solutions was defined. In the studies not crosslinked chitosan as well as chitosan cross-linked with a chemical cross-linking agent - glutaraldehyde and ionic cross-linking agent - pentasodium tripolyphosphate were used. The scope of the research included the determination of pH at which the adsorption process proceeded efficiently, study time, in order to designate the time, after which the reaction equilibrium is reached and to determine the kinetics of the adsorption process and constants in the Langmuir 2 equation. The work sets maximum sorption capacity of the sorbent non-crosslinked and two crosslinked sorbents. Based on these results, it was found that the highest removal efficiency of dye RB 5 was obtained for chitosan crosslinked with ion agent - pentasodium tripolyphosphate. The maximum sorption capacity of the sorbent amounted 1125.7 mg / g d.m. of chitosan.
