摘要: Abstract The nonviable biomass of Aspergillus niger, japonica, Rhizopus nigricans, arrhizus, and Saccharomyces cerevisiae were screened for biosorption textile dyes. selected anionic reactive dyes C.I. Reactive Black 8, Brown 9, Green 19, Blue 38, 3. Experiments conducted at initial dye concentration 50, 100, 150 200 mg/L. effect concentration, dose biosorbent loading, temperature, pH on adsorption kinetics was studied. S. R. nigricans good biosorbents 50 mg/L, 1 g% (w/v) loading 29 ± 1 °C. adsorbed 90–96% in 15 min, 20 °C 6.0. data showed an optimal fit to the Langmuir Freundlich isotherms. maximum uptake capacity (Qo) range 112–204 mg/g biomass.
