方法:测定V - CTS对金属离子的等温吸附线,并用FT - IR法研究v - CTS与金属离子形成的配合物的结构特征。
Method: the adsorption isotherms of metal ions on V-CTS were obtained, and the structures of complexes of V-CTS with metal ions were studied by FT-IR spectroscopy.
氪不能被Pt F 6氧化。在无水氟化氢(aHF)溶液中,氙能形成过渡金属离子的配合物,而氪不行。
Krypton is not oxidized by PtF6, and in the solvent anhydrous HF (aHF), forms no complexes with transition-metal ions as xenon does.
主要原因可能是形成配合物后电子由配体流向配位的中心阳离子,增加了电子的转移能力。
Thus could be resulted from the complexation by which increases the electron density of the metal ion through partial sharing of its positive charge with donor groups.
