摘要
对NO-2 三乙醇胺对B Z振荡反应 ,NO-2 的浓度的对数 1n[NO-2 ]与诱导期倒数的对数 1n(1/tin)有良好的线性关系 ,线性范围为 3× 10 -5～ 3× 10 -3 mol·L-1,在此浓度范围内 ,NO-3 、三乙醇胺均无影响 ,该体系重现性好、灵敏度高、操作简单。获得诱导期、周期的表观活化参数Ein、Ep 分别为 4 1 86、5 7 0 1kJ·mol-1。
The influence of NO^-_2-triethanolamine on B-Z oscillatory reaction was studied.The results show a linear relationship between ln(1/t_(in))and 1nc_(NO_2)^- in the linear erange of 3×10^(-5)～3×10^(-3) mol·L^(-1).Within the range,NO^-_3 and triethanolamine have no influence.Therefore its a kinetics analytical measure system with good reappearance,high sensitivity and simple operating condition.The apparent activation parameter of induction period(E_(in))and oscillatory period(E_p)are obtained,E_(in)=41.86 kJ·mol^(-1),E_p=57.01 kJ·mol^(-1).Also the possible mechanism of the induction period with existing NO^-_2 was discussed in detail.
