摘　　要：研究了酿酒酵母对重金属离子Mn2+的生物吸附特性,考察了pH值、吸附时间、酿酒酵母添加量等条件对酿酒酵母吸附废水中Mn2+能力的影响。结果表明:当废水的初始pH值为5,吸附时间为60 min,酿酒酵母添加量为6 g/L时,酿酒酵母对Mn2+的吸附效果最理想。酿酒酵母添加量对吸附有一定影响,但不宜过大。In this paper the characteristics of manganese（ Ⅱ） biosorption by saccharomyces cerevisia are studied.The effects of environmental factors on metal biosorption are studied,including initial pH value,sorption time and dosage of saccharomyces cerevisia. The results show that the biosorption equilibriums of saccharomyces cerevisia to Mn^2 ＋is optimal when pH = 5,sorption time is 60 min and the biomass concentration is 6 g /L. The dosage of saccharomyces cerevisia could affect the biosorption,but it is inadvisable to add too much dosage.
