The present invention relates to insoluble compositions, which are capable of removing metal (e.g. selectively) from solution (e.g. Fe3+ from a liquid nutrient medium so as to lower the Fe3+ content to less than 0.1 µM); the insoluble compositions comprise: a suitable insoluble carrier and organic co-ordinating sites covalently fixed to the surface of said carrier, said co-ordinating sites being capable of chelating Fe3+, Th4+ and/or UO22+.
本发明涉及不溶性组合物,该组合物能够(例如选择性地)从溶液中去除
金属(例如从液体营养
培养基中去除Fe3+,从而将Fe3+含量降至0.1 µM以下);不溶性组合物包括:合适的不溶性载体和共价固定在所述载体表面的有机配位位点,所述配位位点能够螯合Fe3+、Th4+和/或UO22+。
