| 摘 要： | 研究了啤酒酵母对 Cr( )的吸附作用。当 p H=2时吸附效果最好 ,振荡 30 min吸附基本可达平衡。常见离子Na+、Ca2 +、Mg2 +、Cl-等对吸附影响不大。在一定浓度范围酵母菌对 Cr( )的吸附符合 Freundlich和 Langmuin等温吸附模型。随酵母菌和 Cr( )接触时间的增加 ,Cr( )被还原为 Cr( )。

| Abstract: | The biological adsorption of yeast tochromium Ⅵ was studied in the paper. The adsorption quantity is biggest in pH=2. The adsorption reached balance after half an hour. Na+ ,Ca2+ ,Mg2+ ,Cl- ions have no significant effect to the adsorption. The adsorption accorded with Freundlich and Langmuin isothermal adsorption models. Chromium Ⅵ can be deoxidied to chromium Ⅲ by beer yeast. |
