The adsorption of the Chchory particles on Cu(II), Pb(II) and Cd(II) ions were examined by measurements of the adsorption percentage under various condition of temperature, pH, times, heavy metal concentration. Each of 100ml sample solution of Cu(II), Pb(II) and Cd(II) ions mixed with 2g of the Cichory under stirring in shaking water bath for minutes. The solutions were then filtered and pretreatmented according to water pollution official test methods. The concentrations of Cu(II), Pb(II) and Cd(II) ions in the solution were determined by the atomic adsorption spectrophotometer. As a results, the most effective pH of the adsorption of Cu(II), Pb(II) and Cd(II) was 9. With increasing the concentration of heavy metals the amount of adsorption on Cichory was increased. The adsorption equilibrium of Pb(II) and Cd(II) ions were reached to equilibrium by shaking for about 40 minutes. The absorptivities were 85%, 75% respectively.
