计算了乌洛托品的拉曼光谱,并以银溶胶为活性基底研究了乌洛托品的表面增强拉曼光谱(SERS)。研究了氯化钠作为促凝剂时的增强效果,结果表明对于银溶胶氯化钠有很好的优化作用。测量不同浓度乌洛托品溶液的SERS,当乌洛托品水溶液浓度低至10-8 g/mL时,依然可以得到明显的拉曼光谱信号。选择1052cm-1处的拉曼特征峰作为研究对象,建立了乌洛托品SERS特征峰强与水溶液浓度之间的函数关系。将这种乌洛托品的检测方法应用于粉丝样品的检测之中,检测下限为10-6g/mL。此种方法操作简便快捷,在粉丝中乌洛托品的快速定性检测方面具有特有的优势。
The Raman spectrum of urotropine was calculated and the surface enhanced Raman spectroscopy (SERS) of urotropine was studied using silver sol as active substrate. The enhancement effect of sodium chloride as a coagulant was studied. The results showed that the silver sol had good optimization effect on sodium chloride. When SERS was measured at different concentrations of urotropine, significant Raman spectra were still obtained when the concentration of urotropine was as low as 10-8 g / mL. The Raman peak at 1052 cm-1 was selected as the study object to establish the relationship between the characteristic peak intensities of SERS and the concentration of aqueous solution in urotropin. This method of urotropin detection method used in the detection of fans, the detection limit of 10-6g / mL. This method is simple and quick to operate and has unique advantages in the quick and qualitative detection of urotropine in its fans.
