关于艾叶的电化学指纹图谱研究

Study on the Electrochemical Fingerprint of Mugwort

研究了艾叶-BrO-3-Mn2+-H+-丙酮组成的振荡反应体系在恒温条件下进行的振荡反应。测定了不同浓度、不同温度下艾叶的振荡反应行为,得到了不同温度、浓度下反应的诱导期,振荡周期及考察了参与物质组分浓度及转速对振荡反应的影响。结果表明:在固定其它反应物浓度、温度的条件下,艾叶的振荡浓度区间为10.27～38.18 mg/mL,艾叶振荡体系诱导期表观活化能为67.18 kJ/mol。

The oscillation reaction in mugwort - Acetone - KBrO3 - MnSO4 - H2 SO4 was studied using oscillating technology. The oscillating behaviors of mugwort were discussed at different concentrations and temperatures. The osclillating induction phase and oscillating period of this system were recorded. The effect of the concentration of ractants and the rotational speed was studied. The results showed that the optimum dose of mugwort was 10. 27 - 38.18 mg/mL and the apparent activation energies for induction phase was 67. 18 kJ/mol.
