【Abstract】 The effects of many kinds of metal ions on algae decoloring azo dyes with different molecular structures were studied. The results showed that the types and concentrations of metal ion played important roles in the process of algae decoloring azo dyes, the weight and structure of azo dye molecular could affect their decolorization in the system. It was found that the systems of algae with metal ion had much more rapid velocity and higher efficiencies for decoloring azo dyes in water than algae alone. Simultaneously the decolorization difference of azo dyes in the system was also discussed.更多还原
