摘要: 选取提取时间、提取方式、提取溶剂以及提取溶剂用量这四个重要的提取参数,采用正交实验设计对茶叶中有机磷类农药残留的提取技术进行优化,减少了试验次数,提高了实验效率。应用SAS数据分析软件对实验数据进行分析,准确迅速得到了茶叶中有机磷类农药残留的提取最佳条件是用10βml乙酸乙酯作提取溶剂,震荡提取10 min。

Abstract: The thesis optimized the extraction of organophosphorous(OPPS) in tea with orthogonal design of experiment. The specific volume of OPPS as variable was chosen and four important factors such as extraction time,extraction methods, solvent extraction, dosage of solvent extraction were selected. The experiment data was analyzed by statistical analysis system. Through the analysis, we got the best conditions of the extraction of OPPS in tea. The best condition of extraction of organophosphorous is 10 ml ethyl acetate with shake in 10 min for extraction.

Key words: tea, organophosphorous, orthogonal design of experiment, statistical analysis system
