摘 要: 研究了海洛因对Belousov Zhabotinsky(B Z)振荡反应的影响 ,结果表明 :海洛因的加入明显地改变了振荡体系的周期和振幅 ,即对振荡体系产生扰动 ,扰动的浓度范围为 1.8× 10 -8~ 2 .1× 10 -3 mol/L ,且海洛因的浓度分别在 3.8× 10 -6~ 2 .8× 10 -5mol/L和 0 .9× 10 -6~ 2 .9× 10 -5mol/L范围内与振荡周期改变值ΔT和振幅改变值ΔA均呈现良好的线性关系 ,相关系数分别为 0 .9931和 0 .974 6。据此 ,建立了测定海洛因的新方法。 The effect of heroin on the Belousov-Zhabotinsky oscillating chemical reaction was studied. Results show that the addition of heroin can perturb both the oscillating period and amplitude over the heroin concentration range from 1.8 x 10(-8) to 2.1 x 10(-3) mol/L. The changes of the oscillating period and the amplitude are linearly proportional to the concentration of heroin in the range of 3.8 x 10(-6) similar to2.8 x 10(-5) mol/L and 0. 9 x 10(-6) similar to2.9 x 10(-5) mol/L with the regression coefficients of 0.9931 and 0.9746, respectively. The proposed method was successfully applied to determine heroin.
