Fungal mycelium pellets of Aspergillus niger 405 were used for adsorption of different metal ions. The biosorption of Cu2+, Zn2+, Ni2+ and CrO42– was studied over a range of metal ion concentrations, adsorption time, pH and co-anions. The process of uptake obeyed both the Langmuir and Freundlich isotherms. The results showed better biosorption for the first three metal ions at pH ranging from 4 to 6. On the contrary, pH values from 3 to 7 had no influence on sorption of chromium. Comparison of metal uptake in single and multi-component aqueous solutions of Cu-Zn-Ni-Cr was discussed. Fungus Aspergillus niger 405 showed a good affinity for binding of Cu2+, Zn2+ and Ni2+ ions in single, while in multi-component solution it occurred only for copper and zinc.
