大学本科生毕业设计(论文)摘 要近年来，随着化学农药的使用和普及，粮食产量得到了大幅度的提升，但由于农药的不合理使用和自身的毒性，也给人类健康和生存环境带来了严重的威胁。本文详细介绍了化学农药在不同介质中的残留以及目前农药分析检测中常用的前处理方法，以及甲氨基阿维菌素苯甲酸盐（以下简称甲维盐）的性质和在防虫害方面的应用，并建立了甲维盐在玉米样品中的残留检测分析方法，主要研究结果如下：采用 QuEChERS 作为样本前处理方法，HPLC-MS/MS 作为检测方法，对玉米样品中的甲氨基阿维菌素 B1a 进行检测。试验结果表明：在 0.002-1 mg/L 稀释范围内，阿维菌素 B1a 质量浓度与响应峰面积呈现出了良好的线性关系，R2＞0.99，玉米样品的三种基质（玉米轴、玉米粒、玉米秸秆）在0.01 mg/kg、0.1 mg/kg、1 mg/kg 三种添加水平下，测得回收率为 84 %-105 %，相对标准偏差为 2.3%~6.7%，最低检测浓度为 0.01 mg/kg，满足《农作物中农药残留试验准则》中的规定，适合于甲维盐在玉米上的残留分析研究。- I -关键词： 甲氨基阿维菌素苯甲酸盐，残留检测分析，QuEChERS，高效液相色谱-串联四极杆质谱大学本科生毕业设计(论文)Study on Residue Analysis of 5.7% Emamectin Benzoate on CornAbstractIn recent years, with the use and popularization of chemical pesticides, food production has been greatly improved, but due to the unreasonable use of pesticides and its own toxicity, it also poses a serious threat to human health and the living environment. This article details the residues of chemical pesticides in different media and the current pretreatment methods commonly used in pesticide analysis and detection, as well as the properties and application of Emamectin Benzoate in pest control, and a method for the detection and analysis of Emamectin Benzoate in corn samples was established. The main results are as follows:QuEChERS was used as the sample pretreatment method, and HPLC-MS/MS was used as the detection method to detect the Emamectin B1a in the corn samples. The test results show tha...
