化学传感器提供了方便、快捷、廉价的分析检测有毒重金属离子的方法,具有很高的灵敏度和选择性。检测对象专一的反应型光化学传感器受到越来越多的关注。本文综述了识别Hg2+的反应型光化学传感器的最新研究进展。按照化学反应类型来分类,包括汞促进脱硫和脱硫醇反应、汞促进硫脲衍生物脱硫化氢分子内成环反应、羟汞化及加汞化反应等。
Chemical sensors provide a convenient, fast and inexpensive method of detecting toxic heavy metal ions with high sensitivity and selectivity. Detection of specific reaction type photochemical sensor receives more and more attention. This review summarizes recent advances in the identification of Hg2 + -based reactive photochemical sensors. Classified according to the types of chemical reactions, including mercury to promote desulfurization and sweetening reaction, mercury to promote thiourea derivatives hydrogen sulfide intramolecular cyclization reaction, mercury and mercury and mercury reaction.
