The paper deals with the application of chitosan in the form of beads to the removal of copper, zinc and chromium ions from water. The main element of the experimental equipment was a glass column, 5 cm in diameter and 30 cm high. The column was filled with chitosan beads. The research was car-ried out in one-, two- and three-component solutions, at the initial concentrations c0 ranging from 50 to 70 mg/dm3.In the description of metal sorption kinetics, the second-order equation was used. It well describes experimental data (its correlation coefficient ranged from 0.94 to 0.99).
