| 摘 要： | 为了研究微生物对水溶液中金属离子的去除机理，本文采用原子吸收法对菌株E2吸附镉离子过程中的菌体表面吸附量和菌体内累积量进行了测试。测试结果表明，菌株E2对镉离子既有菌体表面生物吸附作用，也有体内生物累积作用，其中表面吸附作用大于体内累积作用。 |

| Abstract: | In order to study the mechanism of removal metal ion from solution by microbe, the biosorption and biological accumulation of strain E2 removal cadmium were tested by atomic absomtion. The results show strain E2 can remove cadmium by not only biosorption but also biological accumulation and the biosorption plays a main role. |
| Keywords: | atomic absorption biosorption biological accumulation |
