目的:研究了白腐菌菌体吸附染料特性、影响因素及吸附机理.方法:采用分光光度法、吸附热特性、傅立叶变换红外光谱(FTIR)分析等系统地对菌体吸附特性及机理进行研究.结果:白腐菌BP对不同类型的染料有不同的吸附效果,240min内染料RBBR脱色率能达82.35%.菌体对RBBR的合适吸附条件为:温度28℃、转速100r/min、菌体粒径小于60目.吸附符合Freundlich模式,为多分子层吸附.菌体吸附染料主要通过菌体表面的羟基、羧基、胺基及磷酸基团与染料分子以共价键、离子交换或氢键结合来进行.结论:利用白腐菌菌体能有效的对部分染料进行吸附脱色.

The characteristics, affecting factors and mechanism of adsorptive removal of dyes by dead white rot fungus were investigated. Methods： The spectrophotometric method, the characteristics of heat of adsorption and Fourier Transform Infrared Spectroscopy （FTIR） spectra were used to analyze systematically the characteristics and mechanisms of biosorption by dead fungus. Results： The results showed that different dyes could adsorbed by dead Pleurotus ostreatus BP effectively, especially Remazol Brilliant Blue R （RBBR）, whose decolorization ra...
