摘要
为了快速测定白酒年份酒中乙酸的体积分数, 采用3维荧光光谱结合交替拟合残差算法, 首先将不同体积分数的乙酸乙醇水溶液的3维荧光光谱作为校正集, 然后将白酒的3维荧光光谱作为预测集, 利用交替拟合残差算法进行解析分辨, 采用标准添加法来验证结果的准确性。结果表明, 预测体积分数与真实体积分数的相关系数为0.9926, 平均回收率为101.97%;3维荧光光谱结合交替拟合残差算法可以快速有效地测定白酒年份酒中乙酸的体积分数。这一结果对白酒年份酒中单体体积分数的检测是有帮助的。
Abstract
In order to quickly determine the volume fraction of acetic acid in Chinese aged liquor, 3-D fluorescence spectroscopy and alternate fitting residual algorithm were used. Firstly, 3-D fluorescence spectra of different volume fraction of acetic acid of ethanol aqueous solution was used as the calibration set. 3-D fluorescence spectrum of liquor was used as the predicted set. Alternate fitting residual algorithm was used to analyze. Standard addition method was used to verify the accuracy of the results. Through theoretical analysis and experimental verification, the results show that, correlation coefficient between the predicted volume fraction and the experimental volume fraction is 0.9926. Average recovery percentage is 101.97%. 3-D fluorescence spectrometry combined with alternate fitting residual algorithm can quickly and effectively determine the volume fraction of acetic acid in Chinese aged liquor. This result is helpful for the detection of monomer volume fraction in Chinese aged liquor.
