Abstract

In this paper, isatin-hydrazone was synthesized using SBA-Pr-N-Is-But-SO3H as nanocatalyst via the two-component reaction of isatin with hydrazine hydrate in an expeditious reaction with high yield of production. The sensing properties were evaluated in EtOH: H2O (1:9) for the different cation (K+, Ca2+, Na+, Cu2+, Zn2+, Cr3+, Mn2+, Co2+, Al3+, Pb2+, Ag+, Cd2+, Ni2+, Hg2+, and Mg2+). The obtained results revealed that these compounds could be applied as chemosensor for the sensitive detection of Hg2+ and Ag+ ions using UV–Vis spectroscopy and fluorescence spectroscopy, respectively. The detection limit was calculated to be 1.17 × 10–6 M for Hg2+ ions and 1.4 × 10–6 M for Ag+ ions. Also, isatin-hydrazone was treated with 4-flurobenzaldehyde to obtain 4-fluorobenzaldehyde-N-(2-oxo-1,2-dihydro-3H-indole-3-indole-3-ylidene)hydrazone which could sensitively select Hg2+ ions among different ions using fluorescence spectroscopy. The detection limit of the colorimetric sensor to detect the Hg2+ ions is 3.6 × 10–6 M. At the end of the reaction, the nanocatalyst was recovered and reused.

异汀-酰肼对 Ag+和 Hg2+离子化学传感器活性的光谱学研究
本文使用 SBA-Pr-N-Is-But-SO3H 作为纳米催化剂,通过异汀与水合肼的双组分反应合成了异汀腙,反应迅速,产率高。在 EtOH: H2O(1:9)中评估了不同阳离子(K+、Ca2+、Na+、Cu2+、Zn2+、Cr3+、Mn2+、Co2+、Al3+、Pb2+、Ag+、Cd2+、Ni2+、Hg2+ 和 Mg2+)的传感特性。研究结果表明,这些化合物可用作化学传感器,分别利用紫外可见光谱和荧光光谱灵敏地检测 Hg2+ 和 Ag+ 离子。经计算,Hg2+ 离子的检测限为 1.17 × 10-6 M,Ag+ 离子的检测限为 1.4 × 10-6 M。此外,用 4-氟苯甲醛处理异汀腙可得到 4-氟苯甲醛-N-(2-氧代-1,2-二氢-3H-吲哚-3-吲哚-3-亚基)腙,该腙可利用荧光光谱在不同离子中灵敏地选择 Hg2+离子。反应结束后,纳米催化剂被回收并重复使用。
