| 中文摘要 |
| 从发酵工业选取9种废弃的菌丝体,考察其对水中Pb离子的吸附行为。结果表明,其中半数菌丝体对Pb的最大吸附量接近或超过100mg/g干重。对林可链霉菌的吸附等温线和pH值、温度、共存离子等因素影响Pb离子吸附行为的研究表明,该菌丝体对Pb的吸附量随pH降低而升高,温度对吸附的影响不大,共存Cu2+使Pb的吸附量降低,而共存Zn2+无明显影响。 |
| 英文摘要 |
| Nine types of waste biomass from fermentation industry were compared for thier lead uptake capacities. Results showed half of them have a maximum lead uptake close to or higher than 100 mg/g dry weight.Isotherm of Streptomyces lincolnesis and effect factors of it's lead uptake,i.e.pH value,temperature and coexisting ions were studied.It was indicated that the lead uptake capacity of Str.lincolnesis increases with pH value decreae;temperature slightly affects lead ion uptake; coexisting copper ion in the solution causes the lead uptake to decrease,while coexisting zine ion has no effect. |
