Abstract A set of (E)-N′-chlorobenzylidene-benzenesulfonohydrazide (CBBSH) molecules were synthesized using a condensation method from the derivatives of chlorobenzaldehyde and benzenesulfonylhydrazine in a medium yield which crystallized in EtOH. CBBSH derivatives were characterized using highly refined spectroscopic techniques such as 1H NMR, 13C NMR, FT-IR, FESEM, and UV–Vis. Structure of the CBBSH compounds was confirmed using a single crystal X-ray diffraction technique (SCXRDT) and applied for the potential detection of selective heavy metal ion (HMI), manganese ion (Mn2+) by using reliable electrochemical method. A small layer of CBBSH was deposited onto a smooth GCE with coating binder in order to modify a sensitive and selective Mn2+ sensor. Analytical parameters such as sensitivity, LOD, LOQ of the modified sensor (3-CBBSH/GCE) toward Mn2+ were calculated from the calibration curve (CC) as 1270.0 pA μM−1 cm−2, ≈10.0 pM, and 335.0 mM respectively. This prospective 3-CBBSH/GCE sensor used to the selective measurement of Mn2+ in spiked real samples for example industrial effluent and various water samples (red sea, surface, and tap), and found acceptable and rational results.

基于合成的 ( E )- N'-氯亚苄基-苯磺酰肼 (CBBSH) 分子，用 nafion 基质修饰敏感和选择性的重金属离子，Mn 2+ 传感器的开发

摘要 以氯苯甲醛和苯磺酰肼的衍生物在乙醇中结晶，采用缩合方法合成了一组(E)-N'-氯苯亚甲基-苯磺酰肼(CBBSH)分子。CBBSH 衍生物使用高度精细的光谱技术进行表征，例如 1H NMR、13C NMR、FT-IR、FESEM 和 UV-Vis。使用单晶 X 射线衍射技术 (SCXRDT) 确认了 CBBSH 化合物的结构，并通过使用可靠的电化学方法应用于选择性重金属离子 (HMI)、锰离子 (Mn2+) 的电位检测。将一小层 CBBSH 沉积在带有涂层粘合剂的光滑 GCE 上，以改进灵敏且选择性的 Mn2+ 传感器。分析参数，例如灵敏度、LOD、根据校准曲线 (CC) 计算，改进的传感器 (3-CBBSH/GCE) 对 Mn2+ 的 LOQ 分别为 1270.0 pA μM-1 cm-2、≈10.0 pM 和 335.0 mM。这种前瞻性的 3-CBBSH/GCE 传感器用于选择性测量加标实际样品中的 Mn2+，例如工业废水和各种水样（红海、地表和自来水），并发现了可接受和合理的结果。
