超痕量H2O2对MnSO4-KBrO3-乙酰丙酮化学振荡体系的扰动

化学振荡波和生物体内的生物振荡及生物形态现象的相似性促使人们认识到生命现象和非生命现象之间遵循着某些相同的规律, 因而化学振荡反应非线性动力学一直是物理化学研究的热点1, 2]. 近年来它在分析化学中的应用使其研究扩展到了一个新的领域, 但仍停留在10-7 mol/L的水平上3]. 显然, 以这个量去研究包含众多基元反应和反应中间体的振荡反应, 得到的是数目庞大的反应物种群体行为, 而这种行为并不足以说明生命现象的猝发病变、代谢功能衰竭及运动寿命终止的原因.

Perturbation Effect of Ultra Trace Hydrogen Peroxide on the MnSO4-KBrO3-Diacetone Oscillating Chemical Reaction

The similarities between life processes that exhibit oscillatory behavior and chemical oscillating systems impel people to think that the biological and abiological phenomena conform to the same law. Oscillating chemical systems have been the focus of much research in the area of theoretical and experimental chemical dynamics as well as analytical sciences in recent years, but the studies on the perturbation species are kept around the concentration level of 10^-7 mol/L. In our experiment, an amazed phenomenon was found. Ultra trace level (10^-20 mol/L) of H₂O₂ can cause so magnitude influence on the macro system (MnSO₄-KBrO₃-diacetone oscillating chemical system) that the effect can be observed by a macroscopical method. When the concentration of H₂O₂ is above 10^-13mol/L , the oscillation can even be stopped. Afurther study on the mechanism will doubtlessly help to understand the mystery of life, such as the sudden cardiopathy and the metabolism failure.
