Study on optimization of extraction and detection method for residual organochlorine pesticides in Saposhnikovia divaricata
摘要
Abstract
To study on the status of organochlorine pesticide residues in northeast authentic medicinal herbs Saposhnikovia divaricata.The extraction conditions were optimized by screening extraction solvent, extraction method and orthogonal design.The residual amount of six kinds of organochlorine pesticides in Saposhnikovia divaricata was analyzed through choosing the best way to clean up, adjusting the temperature rise procedure and the carrier gas flow rate to determine the optimum chromatographic conditions.The results showed a mixed solvent of acetone and methylene chloride were used as extraction agent, by ultrasonic extraction and concentrated sulfuric acid sulfonation method for purification to prepare the test solution.The analysis method is suitable for strong acid tolerance, and meets the requirements of pesticide residue analysis.This method was simple and rapid.It could provide reference for the detection of organic chlorine and other pesticide residues in Chinese herbal medicines.关键词
