    Abstract

    This paper reports on the adsorption of Cr(VI), Cu(II) and Pb(II) from laboratory solution by the use of Chelex 100 (C100) and Amberlite IRA400 ion exchange resins. Metal loading at initial pHs of 3 to 8 at 1-100 mg/L were studied based on Qmax and K1 values of the Langmuir and Freundlich isotherm. models, respectively. Lead was sorbed the most (Q max = 75.19 mg/g, at pH 6), followed by Cu (Qmax = 58.07 mg/g, at pH 5) with C100 and Cr (Qmax = 49.02 mg/g at pH 4) with IRA400. Overall adsorption capacity were as follows: Pb(II) > Cu(II) > Cr(VI) and dependent on the initial pHs.
