【摘要】 利用橙皮素对四氮杂大环镍催化的Briggs-Rauscher(BR)化学振荡体系(KIO3-[NiL](ClO4)2-H2SO4-H2O2-MA)的扰动建立测定橙皮素的新方法.其中,四氮杂大环镍配合物[NiL](ClO4)2中的配体L为5,7,7,12,14,14-六甲基-1,4,8,11-四氮杂环-4,11,-二烯.分析结果表明,当橙皮素的浓度在1.5×10-6~1.58×10-4 mol·L-1之间时,抑制时间与加入橙皮素浓度之间有良好的线性关系.文章对各组分浓度的影响进行探讨,从而获得最佳检测浓度,同时运用循环伏安对其扰动机制进行了探讨.更多还原

【Abstract】 The paper reported a new method to detect hesperetin based on the Briggs-Rauscher(BR)oscillating system(KIO3-[NiL](ClO4)2-H2SO4-H2O2-malonic acid)catalyzed by a new macrocyclic nickel complexes.The ligand L in the complex[NiL](ClO4)2is 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradeca4,11-diene. The authors define the inhibition time as a parameter to discuss the influence.As a result,when the concentration of hesperetin is from 1.5×10-6to 1.58×10-4 mol·L-1 there is a linear relationship between the concentration and the inhibition time.In order to find the optimum condition to test the hesperetin the control variable method was used.And through the method of cyclic voltammetry,they can explore the mechanism about the system.更多还原
