which were crystallized in MeOH and then re-crystallized from acetone and EtOAc (50:50). Synthesized molecules were characterized by means of spectroscopic techniques for example 1H NMR, 13C NMR, FTIR, and UV–Vis. A probe was furnished by deposition of little layer of DMPSBSH and DMPSMBSH onto a flat GCE with conducting polymer matrix, Nafion (Nf). This furnished probe was used for the impending detection
摘要 采用简单的缩合方法合成了两个新分子(2,5-二甲氧基-N'-(苯磺酰基)-苯磺酰肼 DMPSBSH 和 2,5-二甲氧基-N'-(苯磺酰基)-4-甲基苯磺酰肼 DMPSMBSH)。 2,5-二甲氧基-苯-1-磺酰氯(DMBSC)和苯磺酰肼(BSH)和4-甲基-苯磺酰肼(4-MBSH)分别以良好的收率在甲醇中结晶,然后在丙酮和乙酸乙酯中重结晶(50:50)。合成的分子通过光谱技术进行表征,例如 1H NMR、13C NMR、FTIR 和 UV-Vis。通过在具有导电聚合物基质 Nafion (Nf) 的平坦 GCE 上沉积少量 DMPSBSH 和 DMPSMBSH 层来提供探针。这种配备的探针通过使用可靠的电流-电压技术用于即将检测的钙离子 (Ca2+)。根据校准曲线计算出的建议探针 (DMPSMBSH/GCE/Nf) 对 Ca2+ 的分析参数(灵敏度、LOD 和 LOQ)分别为 2531
