摘要

Abstract >A rapid, low‐cost, and simple method is proposed based on a miniaturized solid‐phase extraction named microextraction in packed syringe coupled with gas chromatography and mass spectrometry for the preconcentration and determination of some organophosphorous pesticides including diazinon, ethion, and malathion. For the first time, natural nanoperlite is used as a safe sorbent. Based on this technique, the analytes are adsorbed on the solid phase and then eluted by a desorbing solvent. The influence of some important parameters such as the solution pH, type, and volume of the organic desorption solvent on the microextraction efficiency of the selected pesticide technique is investigated. The proposed method showed a good linearity in the range of 1.0–35.0?μg/L for ethion and 0.4–30.0?μg/L for both diazinon and malathion. The limits of detection in the range of 0.1–0.38?μg/L were obtained using the selected ion‐monitoring mode of the mass spectrometer. The reproducibility of the method was found to be in the range of 2.8–8.9% for the studied pesticides. To evaluate the matrix effect, the developed method is also applied to the preconcentration and determination of the selected pesticides in real water samples. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> >快速，低成本和简单的方法基于小型化固相提出填充填充注射器中的微萃取与气相色谱和质谱，用于预浓缩和测定一些有机磷农药，包括二嗪龙，梯子和马拉硫磷。首次使用天然纳米哌耐热剂作为安全吸附剂。基于该技术，分析物吸附在固相上，然后通过解吸溶剂洗脱。研究了一些重要参数，例如溶液pH，型的溶液pH，型和体积和有机解吸溶剂的体积对所选农药技术的微萃取效率进行研究。所提出的方法显示出良好的线性度，范围为1.0-35.0Ω·μg/ L，对于二嗪烯和马拉硫胺，0.4-30.0Ω·0.μg/ L.使用质谱仪的所选离子监测模式获得0.1-0.38Ωμg/ L的检测限。发现该方法的再现性在研究的杀虫剂的范围内为2.8-8.9％。为了评估基质效应，开发方法也应用于预浓缩和测定真水样中所选农药的测定。</ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-35800/'>《Journal of separation science.》</a> <b style="margin: 0 2px;">|</b><span>2018年第10期</span><b style="margin: 0 2px;">|</b><span>共8页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Taghani Abdollah&option=202" target="_blank" rel="nofollow">Taghani Abdollah;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Goudarzi Nasser&option=202" target="_blank" rel="nofollow">Goudarzi Nasser;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Bagherian Ghadam Ali&option=202" target="_blank" rel="nofollow">Bagherian Ghadam Ali;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Arab Chamjangali Mansour&option=202" target="_blank" rel="nofollow">Arab Chamjangali Mansour;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Amin Amir Hossein&option=202" target="_blank" rel="nofollow">Amin Amir Hossein;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Faculty of ChemistryShahrood University of TechnologyShahrood Iran;</p> <p>Faculty of ChemistryShahrood University of TechnologyShahrood Iran;</p> <p>Faculty of ChemistryShahrood University of TechnologyShahrood Iran;</p> <p>Faculty of ChemistryShahrood University of TechnologyShahrood Iran;</p> <p>Faculty of ChemistryShahrood University of TechnologyShahrood Iran;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/159.html" title="化学">化学;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=gas chromatography&option=203" rel="nofollow">gas chromatography;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=microextraction&option=203" rel="nofollow">microextraction;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=nanoperlite&option=203" rel="nofollow">nanoperlite;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=organophosphorus pesticides&option=203" rel="nofollow">organophosphorus pesticides;</a> </p> <div class="translation"> 机译：气相色谱;微萃取;纳米哌耐力;有机磷农药;
