Detection of Mercury Ions in Aqueous Solution by Fluorescence Spectrometry

Abstract

This paper proposes a simpler and operable method to replace the traditional detection method and detect the mercury ion in water samples quickly and easily. Firstly, the rhodamine derivatives are synthetised, then a rhodamine derivative fluorescent molecular probe is constructed and adopted to detect mercury ions in water samples. In order to detect mercury ions in aqueous solutions, the fluorescence spectroscopy was adopted in this experiment, and rhodamine derivatives were used as fluorescent molecular probes. The rhodamine and its corresponding derivatives were used to detect mercury ions in aqueous solutions. Different metal ions and different chlorides were added to the solution of the compound. Only the one with the addition of mercury ion shows a peak at 555 nm. Therefore, it is concluded that the mercury ion derivative has a better response to metal mercury ion.
