摘要
对于工业生产中环己酮含量的测定来说,常用的的气相色谱方法分析速度慢,不能充分满足工艺过程中反馈控制的要求。为了解决此问题,本论文应用近红外光谱法对环己酮含量进行快速测定,分析结果与实际值之间的标准偏差为0.13,能够完全满足相应工业生产中的精度要求。该方法具有测量速度快、分析成本低、无污染、操作简单方便等特点,在所建立分析模型的适用范围内,能对样品进行准确、快速的分析。
For determination of cyelohexanone content in the industrial production, the commonly used gas chromatography method is slow and can not fully meet the technological requirements of feedback Control in the process. To solve this problem, a rapid method for determining cyclohexanone contents by near infrared spectroscopy is described in this paper. The results（ standard error： 0.13） by NIR method are coincident with those determined by reference method （GC）. The NIR method has advantages such as high-speed, lower analysis cost, no pollution and simplicity. In the nrediction range afbuilt ealihratinn rondo] NIIR rnathtod can nhtnin ocwroet rocnltc
