Determination of Cu, Pb, Fe, and Zn in plant component polymers of a hyperaccumulating plant 60293370 Kobayashi, Fumihisa Maki, Teruya 20172455 Nakamura, Yoshitoshi 40019758 Ueda, Kazumasa Phytoremediation is an innovative technology that utilizes the natural properties of plants to remediate hazardous waste sites. For more cost-effective phytoremediation, it is important to utilize a hyperaccumulating plant after phytoremediation, i.e. the recovery of valuable metals and the production of useful materials. In this work, the determination of metals in plant component polymers in a fern, Athyrium yokoscense, as a hyper-accumulating plant was established using steam explosion, Wayman's extraction method, and ICP emission spectrometry. After A. yokoscense plants were treated by steam explosion, the steam-exploded A. yokoscense were separated into four plant component polymers, i.e. water-soluble material fraction, holocellulose fraction, methanol-soluble lignin fraction, and residual lignin fraction. The concentrations of Cu, Pb, Fe, and Zn in these plant component polymers and the dry weights of plant component polymers were measured. These analytical process determining metals in the plants will contribute to not only the evaluation and the efforts of phytoremediation using a hyperaccumulating plant, but also to the development of more effective phytoremediation. 2005 © The Japan Society for Analytical Chemistry. 金沢大学自然計測応用研究センターエコテクノロジー研究部門 金沢大学工学部 日本分析化学会 The Japan Society for Analytical Chemistory 2005-01-01 2017-10-03 eng journal article VoR http://hdl.handle.net/2297/3921 https://kanazawa-u.repo.nii.ac.jp/records/10264 https://doi.org/10.2116/analsci.21.1553 0910-6340 Analytical Sciences 21 12 1553 1556 https://kanazawa-u.repo.nii.ac.jp/record/10264/files/TE-PR-KOBYASHI-F-1553.pdf application/pdf 626.6 kB 2017-10-03
