在B-Z化学振荡系统中观察最大LEs(λ_L)和诱导时间两个参数和水相中痕量铍离子浓度之间的关系,并定量测定了水相中的铍离子,探讨了水相中铍离子可被检测的最佳条件。实验表明,最大LEs指数(Lyapunov)与诱导期之积(λ_LT_i)在3.00×10~(-5)~3.00×10~(-11)mol/L的范围内和浓度的负对数有良好的线性关系,检测限为2.76×10~(-11)mol/L,相关系数为0.9976。结果是令人满意的。此外,还讨论了可能的机理。
The relationship between the maximum LEs (λ_L) and the induction time and the concentrations of trace beryllium ions in the aqueous phase was observed in the BZ chemical oscillation system. The beryllium ions in the aqueous phase were quantitatively determined. The effects of beryllium ions The best condition to be tested. Experiments show that the product of the maximum LEs exponent and the induction period (λ_LT_i) has a good logarithm of the negative logarithm in the range of 3.00 × 10 -5 to 3.00 × 10 11 mol / L The linearity of detection limit was 2.76 × 10 ~ (-11) mol / L with a correlation coefficient of 0.9976. The result is satisfactory. In addition, possible mechanisms are discussed.
