【摘要】 实验发现,Fe-邻菲啰啉体系中存在化学振荡。本文对振荡的规律进行了初步的探讨并提出了有效的振荡抑制剂。添加抑制剂后,邻菲啰啉分光光度法可以在Fe(Ⅱ)存在时,准确测定Fe(Ⅰ)。更多还原

【Abstract】 The experimental results show that there is a chemical oscillation in iron-phcnanthroline system. The behavior of the oscillation is studied, and the efficient depressors of the oscillation have been proposed. When the depressor is added into the solution containing Fe (Ⅱ) and Fe(Ⅲ),Fe(Ⅱ) can be accurately determined by phenanthroline spectrophotometry.更多还原
