摘要

Abstract > This study reports a highly sensitive electrochemical sensor based on Bi film modified glassy carbon electrode (BiF/GCE) for total determination and speciation trace concentrations of copper(II) ions in environmental water samples. Square wave‐adsorptive anodic stripping voltammetric (SW‐ASV) experiment was performed for monitoring selective accumulation of copper(II) with reagent 3‐[(2‐mercapto‐vinyl)‐hydrazono]‐1,3‐dihydro‐indol‐2‐one (MHDI) at pH?9–10. The mechanism of the electrode reaction of Cu 2+ ‐MHDI complex was safely assigned. The sensor exhibited a wide linear range (3.22×10 ?9 –2.0×10 ?7 ?mol?L ?1 ) with lower limits of detection (LOD) and quantitation (LOQ) of 9.6×1 ?10 and 3.22×10 ?9 ?mol?L ?1 , respectively (R 2 =0.9993). The proposed sensor exhibited interference from active metal ions e.?g. Cd, Hg. The performance of the proposed method was compared successfully with most of the reported methods and comparable efficiencies were obtained. The analytical utility of the proposed SW‐ASV method has been successfully validated for trace analysis of copper(II) in environmental water samples. The method offers a precise, accurate approach with good reproducibility, robustness, ruggedness, and cost effectiveness. </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> >本研究报告了一种基于Bi膜改性玻碳电极的高敏感的电化学传感器（BIF / GCE）在环境水样中的铜（II）离子的总测定和物种痕量浓度。进行方波 - 吸附性阳极剥离伏安法（SW-ASV）实验，用于监测试剂3 - [（2-巯基 - 乙烯基）-HYDRAZONO] -1,3-二氢 - Indol-2-的选择性积累铜（II）的选择性积累pH？9-10的一个（mHDI）。安全分配Cu 2 + / sup> -mhdi复合物的电极反应机理。传感器显示出宽的线性范围（3.22×10 Δ9</ sup> -2.0×10 7 </ sup>Δ10），具有下限检测（LOD）和定量（LOQ）为9.6×1 α10</ sup>和3.22×10 Δ9</ sup>？mol？l ？1 </ sup>，分别（R 2 </ sup> = 0.9993）。所提出的传感器表现出来自活性金属离子E.Ω的干扰。 CD，Hg。通过大多数报道的方法和可比性效率成功比较了该方法的性能。已经成功验证了所提出的SW-ASV方法的分析效用，以进行环境水样中的铜（II）的痕量分析。该方法提供精确，准确的方法，具有良好的再现性，鲁棒性，坚固性和成本效益。 </ 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8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=Al‐Harbi Eman A.&option=202" target="_blank" rel="nofollow">Al‐Harbi Eman A.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=El‐Shahawi Mohammad S.&option=202" target="_blank" rel="nofollow">El‐Shahawi Mohammad S.;</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 ScienceTaibah UniversityAl-Madina Al-Mounawara Saudi Arabia;</p> <p>Department of Chemistry Faculty of ScienceKing Abdulaziz UniversityJeddah P.O.
