| 摘 要： | 实验表明,香草醛的最大吸收波长在310 nm处.光谱分析测定的最佳工作范围为0.010～0.080 mg/mL.在乙醇及水溶液中,香草醛的最大吸收波长基本相同,均随时间的增长而波长紫移,吸收值下降,但其乙醇溶液比水溶液稳定.

| Abstract: | It was shown that the maximum absorbing wavelength of vaniilin lay in 310 nm,the optimal range of spectrum quantitative analysis was from 0.010 to 0.080 mg/mL. The maximum of absorbing wavelength of vaniilin dissolved in water and in ethanol lay almost in the same position. The wavelength moved to short wave and the absorbing intensity decreased with time, but vaniilin dissolved in ethanol was staber than that in water. |
