Abstract

A colorimetric probe (L) was prepared and its metal ion sensing properties were investigated. Probe L exhibited obvious colorimetric response toward Hg2+ and Cu2+ with different color changes in water. The association constant for probe L-Hg2+ and probe L-Cu2+ in water containing 0.5% DMSO (v/v) was determined as 5.62 × 107 M−1 and 1.26 × 107 M−1, respectively. The detection limit of probe L for the analysis of Hg2+ and Cu2+ was determined as 0.19 ppm and 0.39 ppm, respectively. Moreover, probe L can be used for selective sensing of Hg2+ and Cu2+ based on the distinct color changes in real samples.
