Abstract

A benzyl carbazate-based colorimetric chemosensor HB (benzyl (E)-2-(2-hydroxy-3methoxy-5-nitrobenzylidene)hydrazine-1-carboxylate) was synthesized and used for relay detection of Cu²⁺ and S²⁻. HB can sense Cu²⁺ by the color variation from yellow to colorless and be used in real sample. HB-Cu²⁺ detected S²⁻ though demetallation with color variation form colorless to yellow. Detection limits of HB for Cu²⁺ and S²⁻ were calculated to be 0.20 and 0.60 μM which are greatly below WHO guidelines (31.4 and 14.8 μM). In addition, HB and HB-Cu²⁺ could detect Cu²⁺ and S²⁻, respectively, without any interference of other ions. The detection processes of HB to Cu²⁺ and S²⁻ were illustrated by ESI-MS, UV-visible spectroscopy and DFT calculation.
