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.
