摘 要: 研究了Cr2O72-对B-Z化学振荡反应的影响.结果表明,Cr2O27-的加入明显改变该振荡反应的诱导期,且诱导期的改变值Δtin与所加入Cr2O72-的浓度有良好的线性关系,线性范围3.45×10-6~6.20×10-4mol·L-1,相关系数为0.9992,对Cr2O72-扰动B-Z振荡反应的机理进行了探讨. The effect of Cr_ 2O 2-_ 7 on the BZ oscillating chemical reaction was studied. The results show that the addition of Cr_ 2O 2-_ 7 can change the induction period of the proposed system and the change of induction period(Δt_ in) is linearly proportional to the concentration of Cr_ 2O 2-_ 7added in the range of 3.45×10 -6~6.20×10 -4 mol ·L -1, with the regression coefficient of 0.999 2. The disturbing mechanism of Cr_ 2O 2-_ 7 on BZ oscillating reaction is discussed.
