TRANSFORMATION OF METAL IONS BY PLANTS

了解重金属在环境中的命运， 与理解金属离子的形态有关， 环境 重金属离子被非生物和 生物过程 重金属的生物去除和转化 细菌、真菌和植物对重金属的吸收 对环境中金属离子的命运的贡献， 在评估金属离子的迁移率时， 在环境中，修复场地的适合性，或 正在进行补救的地点的进展情况。 我们建议描述 利用XAS技术研究了植物对重金属离子的转化， 通过植物组织培养表征Ni和Cr的积累， 细胞壁和植物细胞内。

An understanding of the fate of heavy metals in the environment is linked to an understanding of the speciation of metal ions in the environment. Heavy metal ions are transformed by both abiotic and biotic processes. Biological removal and transformation of heavy metals by bacteria, fungi and plants can have a significant contribution to the fate of metal ions in the environment which must be taken into consideration when evaluating the mobility of metal ions in the environment, the suitability of a site for remediation, or the progress of a site undergoing remediation. We propose to characterize the transformation of heavy metal ions by plants using XAS to characterize Ni and Cr accumulation by plant tissue culture, both on the cell wall and within the plant cell.
