Abstract: The biosorption property onto Pseudomonas aeruginosa was represented by the Langmuir isotherm, and the maximum capacity of Pb(II) was 45 mg g−1 dry weight of bacteria at pH 5. The biosorption capacity of Pb(II) in a binary system increased with increasing Pb(II) concentration, from 0 to 50 mg l−1 in which Cr(III) existed at a constant concentration of 50 mg l−1. This result indicates that there was no competitive adsorption reaction for the same binding sites on the bacterial surface, because the metal properties of Pb(II) and Cr(III) ions differ.
