selective colorimetric chemosensor properties for Cu(II) ions, was synthesized and characterized by NMR and FT-IR spectroscopy. The CHMPMBS chemosensor demonstrated high sensitivity and selectivity toward Cu(II) in an aqueous media in the presence of many other competing cations (Na(I), Mg(II), Al(III), K(I), Ca(II), Cr(III), Mn(II), Fe(III), Fe(II), Co(II), Ni(II), Cu(II), Zn(II), Sr(II), Ag(I), Cd(II)
在这项研究中,合成了 2-[(carbamothioylhydrazono)methyl-phenyl-4-methylbenzenesulfonate (CHMPMBS),它对 Cu(II) 离子表现出选择性比色化学传感器特性,并通过 NMR 和 FT-IR 光谱进行表征。CHMPMBS化学传感器在存在许多其他竞争性阳离子(Na(I)、Mg(II)、Al(III)、K(I)、Ca(II))的情况下,对水性介质中的 Cu(II) 表现出高灵敏度和选择性, Cr(III), Mn(II), Fe(III), Fe(II), Co(II), Ni(II), Cu(II), Zn(II), Sr(II), Ag(I) , Cd(II), Ba(II), 和 Pb(II)。通过与 Cu(II) 形成 1:1 化学计量比 (Cu: CHMPMBS ) 的复合物,开发的化学传感器呈现出从浅黄色到浅色的独特颜色变化绿色
