摘　　要：陶瓷喷墨打印技术的生产制造过程中使用的主要颜料钴蓝,可能释放钴离子到废液中,对人体健康和生态环境造成危害。因此,开发一种能够有效检测废液中钴离子(Co^(2+))水平的荧光探针显得尤为必要。本研究采用久洛尼定和甲酸肼设计并合成了一种席夫碱荧光探针QE,通过荧光衰减实现对Co^(2+)的实时监测。实验结果表明,向QE中加入Co^(2+)后,颜色迅速由黄绿色变为无色,且在QE对Co^(2+)的识别过程中,未受到其他其他金属阳离子的影响。进一步对QE和Co^(2+)的结合模式及检测性能进行探究,结果表明QE与Co^(2+)的化学计量比为2:1,且QE对Co^(2+)的检测限为1.18×10^(-7)M,表明其对Co^(2+)具有优异的灵敏度。本研究制备的QE可用于复杂环境中的Co^(2+)检测,实现陶瓷喷墨打印全流程Co^(2+)检测。The main pigment used in the production and manufacturing process of ceramic inkjet printing,cobalt blue,may release cobalt ions into waste liquid,threatening human health and the ecological environment.Therefore,the development of a fluorescent probe capable of effectively detecting cobalt ions in wastewater is crucial.In this study,a Schiff base fluorescent probe QE composed of alizarin and formic hydrazide was designed and synthesized,which achieved real-time monitoring of Co^(2+)ions through fluorescence decay.The experimental results demonstrated that the addition of Co^(2+)to QE caused a rapid color change from yellow-green to colorless,and it was not affected by other metal cations during the recognition of Co^(2+)by QE.Further exploring the combined mode and detection performance of QE and Co^(2+),the results showed a 2:1 stoichiometric ratio between QE and Co^(2+),and the limit of detection(LOD)for Co^(2+)is 1.18×10^(-7) M,highlighting the probe’s exceptional sensitivity toward Co^(2+).The QE prepared in this study can be applied to detect Co^(2+)ions in complex environments,enabling comprehensive Co^(2+)monitoring throughout the ceramic inkjet printing process.
