Abstract:

Molecular spectroscopy has the advantages of high sensitivity and simple operation. Therefore, it is significant to develop a probe with high selectivity for nickel ions(Ni2+). In this paper, a novel molecular probe was designed and synthesized from rhodamine B, hydrazine hydrate and 2-acetylpyrazine for the detection of Ni2+ with excellent selectivity in aqueous media. Simultaneously, the probe rhodamine B amide derivative(RWZ) can achieve “naked eye” recognition of Ni2+ in aqueous solution. Furthermore, the probe shows high sensitivity to Ni2+ with low limit of detection(0.5 μmol/L), indicating that the probe can be used for detection of Ni2+ in aqueous solution.
