摘要：

设计、合成了1-丁基-2-苯基硫脲吡啶溴化盐（[C4ptpyr]Br）新型的水溶性Hg2+荧光探针，将其用于环境水样中Hg2+的检测。 结果表明，[C4ptpyr]Br对Hg2+识别专一性好，共存离子及pH值对测定影响小。 在pH=7的BR缓冲溶液中，检测线性范围为0.02～4 mg/L(r2=0.999 1)，检出限为0.011 mg/L，回收率为95.2%～102.2%， RSD＜5%。 方法具有灵敏度和准确度高、分析速度快、操作简便等特点，可满足各类水中微量汞的测定要求。

Abstract:

A novel type of fluorescent ionic liquid, 1-butyl-2-phenyl thiourea pyridinium bromide, was synthesized and a new method for determining Hg2+ in aqueous medium was developed. The results show that the method has an excellent selectivity, good linear relationship(r2=0.999 1), recovery 95.2%～102.2%, and low detection limit(0.011 mg/L) in the mass concentration range of 0.02~4 mg/L in BR buffer solution at pH=7. The method is successfully used for Hg2+ determination in natural water.

Key words: Fluorescence spectrometry, fluorescent ionic liquid, fluorescent probe, mercury ion(Ⅱ)
