摘要

Abstract >This study describes the use of diatomaceous earth during solid‐phase extraction as an efficient sorbent for separation and concentration of dodecanol and ethoxylated dodecanol containing 1–9 ethoxyl groups. The efficiency of different eluents was evaluated for model samples which allowed to select methanol and chloroform for tests with river water samples. During model experiments, it was observed that the recovery rates of specific compounds in the studied mixture were influenced by the character of the solvent used for desorption. Hydrophobic compounds, such as dodecanol and ethoxylated dodecanol with 1–3 ethoxyl groups, were eluted by chloroform with 100% efficiency. In case of the remaining compounds, which were more hydrophilic, a 97% recovery rate was achieved during elution with methanol. Such dependencies were not observed in case of river water samples, as the results obtained for both studied sorbent‐eluent systems were comparable. In both variants the recovery of dodecanol and ethoxylated dodecanol containing 1–9 ethoxyl groups ranged from 33 to 99%. </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> >本研究描述了在固相提取过程中使用硅藻土作为一种有效的吸附剂进行分离含有1-9乙氧基的十二烷醇和乙氧基化十二烷醇的浓度。评价不同洗脱液的效率，用于模型样品，其使甲醇和氯仿与河水样品进行测试。在模型实验期间，观察到所研究的混合物中的特异性化合物的回收率受用于解吸的溶剂的特征的影响。用100％效率的氯仿洗脱疏水化合物，例如十二烷醇和乙氧基化十二烷醇，用1-3个乙氧基洗脱。在更亲水的剩余化合物的情况下，用甲醇洗脱期间达到97％的回收率。在河水样品的情况下未观察到这种依赖性，因为研究的研究生的吸附剂系统的结果是可比的。在两个变体中，含有1-9乙氧基的十二烷醇和乙氧基化十二烷醇的回收率范围为33至99％。</ 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>2019年第5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=Zembrzuska Joanna&option=202" target="_blank" rel="nofollow">Zembrzuska Joanna;</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>Institute of Chemistry and Technical ElectrochemistryPoznan University of TechnologyPoznan Poland;</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=diatomaceous earth&option=203" rel="nofollow">diatomaceous earth;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=dodecanol&option=203" rel="nofollow">dodecanol;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=ethoxylated dodecanol&option=203" rel="nofollow">ethoxylated dodecanol;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=liquid chromatography&option=203" rel="nofollow">liquid chromatography;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=solid‐phase extraction&option=203" rel="nofollow">solid‐phase extraction;</a> </p> <div class="translation"> 机译：硅藻土;十二烷醇;乙氧基化十二烷醇;液相色谱;固相提取;
