摘要 综述了铬(Ⅲ)和铬(Ⅵ)化学传感器的原理、类别、研究和应用进展。主要讨论了光化学和电化学铬离子传感器,其中包括光纤传感器、聚氯乙烯(PVC)膜电极、化学修饰电极、固体膜传感器等。铬离子化学传感器具有实时、在线、远距离、自动化连续监测的能力,为金属、食品及废水等样品中铬离子的测定提供了一种快速便捷方法。 A survey is given of the principle, classification, study and application of chemical sensors for chromium(Ⅲ) and chromium(Ⅶ). The optical and electrochemical sensors for chromium ions are discussed, including optical fiber sensors, polyvinyl chloride (PVC) membrane electrodes, chemically modified electrodes, solid state membrane electrodes and so on. These chemical sensors are possessed of real-time, on-line, remote, automatic and co'ntinuous analysis capability and provide a rapid and simple means for the determination of chromium ions in metal, food, waste water etc.
