| 摘 要： | 研究了B－Z振荡体系在各种组不同浓度下周期和振的改变值与加入二苯胺磺酸钠浓度的关系。结果表明第一个周期改变值与加入浓度有良好线性关系，相关系数均大于0．9916。改变组分浓度，可适当提高检测浓度范围同时对反应机理进行了较为深入的探讨。

| Abstract: | The effects of sodium diphenylamine sulfonate on the B-Z oscillating chemical reaction were studied.Under the conditions of different reactants' concentration,the dependence of the period increase and the amplitude decrease on the injected concentration were reported.Results show that the change of the first oscillation period is directly proportional to the concentration of sodium diphenylamine sulfonate,and all of the related coefficients are greater than 0.9916.Experiments indicated that the variations in concentration of the reactants had an effect on the sensitivity and the accuracy for the determination,especially in the concentration of sulphuric acid.The possible reaction mechanism has been studied. |
