黄孢原毛平革菌吸附铅离子机理的研究
- Study on mechanism of lead biosorption by phanerochaete chrysosporium
- 摘要：通过电子显微镜观察和X-射线光电子能谱测定等分析手段研究了黄孢原毛平革菌(Phanerochaetechrysosporium)对Pb2+生物吸附的机理.实验结果表明,该菌种对Pb2+的吸附过程是一个以表面络合反应为主要机理的物理化学吸附过程,同时也存在着离子交换机理,但它并非主要机理.
- Abstract：Phanerochaete chrysosporium exhibited lead adsorption capacity from aqueous solution up to 108.45 mg/g The biosorption mechanism was researched by the electron micrograph and X-rays Photoelectron Spectra The experimental results showed that the main mechanism of lead biosorption was kind of physical chemical process, and metal ions were adsorbed directly on the cell surfaces In addition to surface complex reaction, ion exchange also played a role in the biosorption process, but it was not a main mechanism.
