Removal of anthraquinone dye Acid blue 41 from an aqueous solution by Aspergillus niger mycelia

Organic dyes constitute one of the larger groups of pollutants in wastewater released from textile industries. several method exit for removal of dye pollutants from weastwater. Biosorption is becoming a promising alternative to replace or supplement the present dye removal processes from dye wastewater. In this study, removal of an anthraquinone dye, Acid blue 41, from an aqueous solution by biosorption on dead fungus, Aspergillus niger, was investigated. The initial pH of the dye solution strongly affected the chemistry of both the dye molecules and fungal biomass in an aqueous solution. The effective pH was 6.5. Kinetic studies showed that the biosorption of Acid blue 41on fungal biomass was a fast process. Equilibrium was reached in 35 min.
