Catalytic action of Fe(Ⅱ)-5-nitro-o-phenanthroline on Belozov-Zhabotinskii oscillation reaction

研究了 Ｆｅ（Ⅱ）的 ５－ＮＯ２ｐｈｅｎ配合物对Ｂｅｌｏｚｏｖ－Ｚｈａｂｏｔｉｎｓｋｉｉ振荡反应的催化作用；从与 Ｆｅ（Ⅱ）的 ｐｈｅｎ，ｂｉｐｙ，ｔｅｒｐｙ 配合物的相互比较（催化参数、酸的影响等）出发，对该化合物的催化特点进行了讨论。最后，给出 Ｆｅ（Ⅱ）的 ５－ＮＯ２ｐｈｅｎ配合物催化Ｂ－Ｚ振荡反应各组分的浓度范围和优势区域图。

ln sulphuric acid medium, the Fe(Ⅱ )-5-nitro-o-phenanthroline complex (A) is found to be capable of catalysing the Belozov-Zhabotinskii reaction. By comparing with three other Fe(Ⅱ ) complexes, complex(A)shows some special features in the initial period, amplitude, as well as the period and duration of oscillation. The bromate-malonic acid initial concentration range for oscillation is determined and the domain diagram is plotted.
