禾本红酵母Y-5对结晶紫、孔雀石绿的吸附
Biosorption of crystal violet and malachite green by Rhodotorula graminis Y-5
摘要
Abstract
With a shaker, this paper studied the characteristics of the biosorption of crystal violet and malachite green by Rhodotorula graminis Y-5 under different adsorption time, initial pH, and temperature, as well as the desorption and recycling use of the dyes. The biosorption of crystal violet and malachite green by R. Graminis Y-5 had the peaks (93. 8% and 87. 7% , respectively) at pH 7.0, dye concentration 50 mg · L-1, 150 r · min-1, 30 °C , and lasting 10 hours. After desorption, the biosorption rate of crystal violet and malachite green by R. Graminis was 85.5% and 78.5% , respectively, indicating that the biosorption of crystal violet and malachite green was reversible , and the recycling use of the dyes by R. Graminis was quite good, I. E. , the dyes were renewable and could be recycled. Biosorption could be the mechanism of the decolorization of the dyes. The dyes were mostly adsorbed on the R. Graminis surface -OH. The adsorption process was fast, efficient, and reversible, suggesting that R. Graminis had a high potential for waste water treatment.关键词
