摘要

Abstract > A simple and highly sensitive electrochemical sensor COOH?C4 derived from dicarboxyl‐calix[4]arene modified on a screen printed gold electrode (Au) was developed for the determination of lead ions in water samples. A 3‐mercaptopropionic acid (MPA) monolayer was used as a template on the gold electrode for the surface modification with dicarboxyl‐calixarene. The modified electrodes were surface‐characterized using Fourier Transform infrared spectroscopy (FTIR). The data obtained proved the confirmation of each stage of the electrode modification. The electrochemical analyses of the COOH?C4 electrode showed an enhanced electrocatalytic activity and higher current towards Pb 2+ ions as compared to the bare Au and MPA/Au electrodes. Under optimum conditions, the differential pulse voltammetry response of COOH?C4 displayed a wide linear response ranging from 280–2500?μg/L for Pb 2+ with a detection limit of 6.2?μg/L. In addition, the fabricated electrode showed a high selectivity and stability towards the Pb 2+ ions in presence of possible interfering species. The present method was successfully applied to determine Pb 2+ ions in real samples with satisfactory precision, with a relative standard deviation of 3.12?% and an acceptable recovery of 92?%, which demonstrated the potential application of dicarboxyl‐calix[4]arene modified on electrodes for heavy‐metal sensing. </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> >一种简单且高敏感的电化学传感器COOHαc4衍生自二羧基 - 杯[4] arene在筛选上修改印刷的金电极（Au）是为了测定水样中的铅离子。用二羧基 - 钙甲烯将3-巯基丙酸（MPa）单层用作金电极上的模板。通过傅里叶变换红外光谱（FTIR）表面表征改性电极。获得的数据证明了电极改性的每个阶段的确认。与裸AU和MPA / AU电极相比，COOHαC4电极的电化学分析显示出增强的电催化活性和朝向Pb 2 + </ sup>离子的更高电流。在最佳条件下，COOH的差分脉冲伏安法响应响应显示为PB <SUP> 2 + </ sup>的280-2500Ωμg/ L的宽线性响应，检测限为6.2ΩΩΩ·升。另外，在可能的干扰物质存在下，制造电极向Pb 2 + </ sup>离子呈现出高的选择性和稳定性。本方法成功地应用于以令人满意的精度确定真实样品中的Pb 2 + </ sup>离子，相对标准偏差为3.12Ω％，可接受的92倍的恢复，这证明了潜在的应用Dicarboxyl-Calix [4]在电极上修饰了重金属感测的电极。 </ 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-22546/'>《Electroanalysis》</a> <b style="margin: 0 2px;">|</b><span>2018年第3期</span><b style="margin: 0 2px;">|</b><span>共10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=Nur?Abdul?Aziz Siti Fatimah&option=202" target="_blank" rel="nofollow">Nur?Abdul?Aziz Siti Fatimah;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Zawawi Ruzniza&option=202" target="_blank" rel="nofollow">Zawawi Ruzniza;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Alang?Ahmad Shahrul Ainliah&option=202" target="_blank" rel="nofollow">Alang?Ahmad Shahrul Ainliah;</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>Department of Chemistry Faculty of ScienceUniversiti Putra Malaysia43400 UPM Serdang Malaysia;</p> <p>Department of Chemistry Faculty of ScienceUniversiti Putra Malaysia43400 UPM Serdang Malaysia;</p> <p>Department of Chemistry Faculty of ScienceUniversiti Putra Malaysia43400 UPM Serdang Malaysia;</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/4817.html" title="电化学、电解、磁化学">电化学、电解、磁化学;</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=Calixarene&option=203" rel="nofollow">Calixarene;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=lead&option=203" rel="nofollow">lead;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=electrochemical sensor&option=203" rel="nofollow">electrochemical sensor;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=gold surface&option=203" rel="nofollow">gold surface;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=self-assembled&option=203" rel="nofollow">self-assembled;</a> </p> <div class="translation"> 机译：Calixarene;铅;电化学传感器;金表面;自组装;
