酚类化合物对人的身体健康危害极大,因此,它是三废检測的重点項目之一。如何減少成消除这种危害,是急待解决的課題。为检測酚类化合物,我专业測酚小组,在应用气相色譜法过程中,开始采用老的实驗方法,选择OV—17色譜柱,花了六天时間,进行154次試驗,未找出最佳条件。后来,采用正交設計法,对另一根色譜柱进行試驗,仅用了八个小时,10次試驗,就找到了該色譜 Phenolic compounds on human health great harm, therefore, it is one of the three waste detection key project. How to reduce it to eliminate such harm is an urgent issue to be solved. In order to test the phenolic compounds, I specialized in the phenol determination group. In the application of gas chromatography, we started using the old experimental method. After OV-17 column was selected, it took 154 days to conduct 154 tests without finding the best condition. Later, using the orthogonal design method, another column was tested in just eight hours and ten times to find the chromatogram
