板蓝根细胞壁吸附铅的特性研究

Characteristic of Adsorption of Lead by Cell Wall of Isatis Indigotica Fort

研究了板蓝根根部细胞壁对铅的吸附特性,讨论了pH对吸附公式中参数的影响。结果表明,细胞壁可以大量、快速的吸附铅;酸性溶液可以部分解吸细胞壁上的铅;在接近中性的微酸性环境中吸附最多。

The characters of adsorption of lead by Isatis indigotica Fort, roots cell wall is studied in present investigation. It was found that the cell wall could adsorb a lot of lead very quickly. The adsorbed metal may be partly desorbed by a treatment with acid solution. The capacity reached maximum value at slightly acidic and neutral solution was also discovered.
