摘要

Abstract >In this work, nanocomposites of reduced graphene oxide coated with ZnO were synthesized using a hydrothermal reduction strategy. Nanocomposite was then used as a sorbent for microextraction in a packed syringe, and its application to the extraction of carbamate pesticides from juice samples prior to high‐performance liquid chromatography detection was demonstrated. Factors affecting the enrichment efficiency of the microextraction in a packed syringe procedure were optimized, which included desorption conditions, sample pH, salting‐out effect, washing solution, and sample cycles. Under optimal conditions, the prepared materials exhibited excellent enrichment efficiency for carbamate pesticides. Good linearity existed in the concentration range of 0.5–200 ng/mL, with correlation coefficients of 0.9991–0.9997. The limits of detection of these carbamate pesticides were in the range of 0.23–1.21 ng/mL, and the average recoveries of the analytes at two spiked levels for real‐sample analysis ranged from 90.5 to 104.2% with relative standard deviations of 3.6–5.9%. </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”>摘要</标题> >，使用热热还原策略合成涂覆有ZnO的纳米氧化物的纳米复合物。然后将纳米复合物用作填充注射器中的微萃取物的吸附剂，并在高性能液相色谱检测之前从果汁样品中提取氨基甲酸酯农药的应用。优化了影响填充注射器程序中微萃取的富集效率的因素进行了优化，包括解吸条件，样品pH，盐渍效应，洗涤溶液和样品循环。在最佳条件下，制备的材料表现出氨基甲酸酯农药的优异富集效率。良好的线性存在于0.5-200ng / ml的浓度范围内，相关系数为0.9991-0.997。这些氨基甲酸酯农药的检测限为0.23-1.21ng / ml，实验分析的两个尖刺水平的分析物的平均回收率范围为90.5至104.2％，相对标准偏差为3.6-5.9 ％。</ p> </ abstract> </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>2019年第12期</span><b style="margin: 0 2px;">|</b><span>共9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=Sun Ting&option=202" target="_blank" rel="nofollow">Sun Ting;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Fan Yuwan&option=202" target="_blank" rel="nofollow">Fan Yuwan;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Fan Peizheng&option=202" target="_blank" rel="nofollow">Fan Peizheng;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Geng Fengyun&option=202" target="_blank" rel="nofollow">Geng Fengyun;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Chen Peiyu&option=202" target="_blank" rel="nofollow">Chen Peiyu;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Zhao Feng&option=202" target="_blank" rel="nofollow">Zhao Feng;</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>College of Chemistry and Chemical EngineeringAnyang Normal UniversityAnyang P.
