【摘要】 由于使用了自己研制的原位毛细管样品池,选择了C-C-O伸缩振动谱带作分析线,针对该谱带中心随乙醇水溶液的浓度而移位的问题,提出用峰值位置的强度作喇曼定量分析,使定量分析的准确度提高,在置信水平α=0.05时,浓度测定的置信区间不大于(y-114.88)/75.69 ±3.3(％)更多还原

【Abstract】 Using an in-situ capillary cell, choosing the stretch vibra- tion mode of C-C-O as the analysing band, We studied the quantitative ana- lyse of ethanol aqueous solution. Expermental results show that testing accu- racy of ethanol concentration c reaches a significant range of c± 3.3(％) at the 5 percent significant level.更多还原
