摘要
介绍了一种用721分光光度计法测定白酒中甲醇含量的方法。实验获得测定白酒中甲醇含量的最佳条件,且其准确度和灵敏度都满足要求;同时对所测2种白酒中甲醇含量进行了对比分析,结果表明,白酒样工作曲线所得两种白酒甲醇含量均在0.006—0.008 g/100 mL之间,所测白酒样品的甲醇含量均符合国家标准,且该测定方法误差小、精度高。
A method of methanol content determine using 721 spectrophotometry is introduced. A optimal condition is obtained by experiment of methanol content determine of white spirits, and its veracity and sensitivity can satisfy requirement. Simuhaneously, a contrast analysis is finished using the results of methanol content determine of two kinds of white spirits. It shows that the methanol content of the white spirits is between 0. 006 g/100 mL and 0. 008 g/100 mL by experiment curve of the white spirits sample. The methanol content of white spirits sample is according with requirement of Chinese standard. The error is small and the veracity is well using this method.
