错误的AMD管理带来环境和生态风险.

研究的目的:

作为四环素化物 (TC) 吸附剂的原料,研究型菌 (PMD).
为了实现PMD的安全管理和解毒.

主要方法:

在不同温度下对PMD进行热解,以产生生物炭 (PMD-BCs).
描述PMD-BCs的特性 (表面积,孔隙体积,稳定性).
在不同条件下评估PMD-BCs的TC吸附能力.

主要成果:

热解完全消除了PMD中的危险污染物.
较高的热解温度增加了PMD-BCs的BET表面积和孔积.
随着热解温度和溶液pH值的增加,TC吸附能力增加,在pH值10时达到71.1 mg/g.

结论:

通过热解,PMD可以被排毒并转化为有效的TC吸附剂.

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
