摘　　要：以四氮杂大环配合物[NiL](ClO4)2作为催化剂构建Briggs-Rauscher非线性化学振荡体系来实现对丹皮酚的检测,其中[NiL](ClO4)2中的L为5,7,7,12,14,14-六甲基-1,4,8,11-四氮杂环-4,11-二烯.向振荡体系加入一定浓度的丹皮酚溶液后,振荡图谱出现振荡受到抑制,并在一定的抑制期(tin)后振荡恢复的现象.将tin与丹皮酚浓度之间建立关系发现,当加入体系的丹皮酚浓度在5.0×10^-6~2.0×10^-5 mol·L^-1区间时,抑制期与加入的丹皮酚浓度呈一次线性关系;当丹皮酚浓度在2.0×10^-5~8.75×10^-5 mol·L^-1区间时,抑制期与加入的丹皮酚浓度呈新的一次线性函数关系.此外,通过对BR体系中的各个底物浓度与抑制时间建立的数据关系进行分析,探索出了扰动实验的最佳体系浓度.In this paper,tetraaza-macrocyclic complex[NiL](ClO4)2-catalyzed Briggs-Rauscher oscillation was used to determine paeonol,in which ligand L in[NiL](ClO4)2 was 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene.After a certain concentration of paeonol solution was added to the oscillating system,the oscillation pattern was suppressed and the oscillation resumed after a certain period of inhibition time(tin).The relationship between tin and paeonol concentration was established and it was found that when the paeonol concentration added to the system was in the range of 5.0×10^-6-2.0×10^-5mol·L^-1,the inhibition period showed a linear relationship with the added paeonol concentration.When the concentration of paeonol was in the range of 2.0×10^-5-8.75×10^-5mol·L^-1,the relationship between the inhibition period and the added paeonol concentration presented a new linear function.In addition,the optimal system concentration of the perturbation experiment was explored by establishing the data relationship between the substrate concentration and the inhibition time.
