Removal of Cr VI , Cu II , Ni II and Remazol Blue RB from aqueous solution by biosorption on dead fungus, Aspergillus versicolor, was investigated. The initial concentrations were 50-150 mg L-1 for metal ions and 25-700 mg L-1 for the dye in the removal tests for each of these pollutants. The highest single Cr VI , Cu II and Ni II yields removed were 15.82 % pH 6 , 28.47 % pH 5 , and 14.59 % pH 6 respectively, and RB yield was 91.89 % pH 5 , 73.20 % pH 6 in optimum conditions. The initial heavy metal ions and dye concentrations were about 50 mg L-1 and 100 mg Lfor binary effects of heavy metal ions and the dye, respectively. In the experiments for the binary biosorption of the metal ions and the dye, the maximum yields of Cr VI , Cu II , and Ni II were 17.76 %, 22.71 %, and 22.74 %, and the maximum RB yields were 21.23 % pH 6 , 61.66 % pH 5 and 51.66 % pH 6 , respectively. This is the first report on biosorption of single and binary heavy metal ions and/or dye by non-living biomass of A. versicolor}, number={1}, publisher={Ankara University}
