Zusammenfassung: | Zhao, J.; Tan, Z.; Gao, Q.; Xu, Y.; Jiang, S.; Liu, J.; Tan, K., and Ashraf, M.A., 2018. Rapid determination of mercury speciation in marine products by molecular spectrometry. In: Ashraf, M.A. and Chowdhury, A.J.K. (eds.), Coastal Ecosystem Responses to Human and Climatic Changes throughout Asia. A method is developed for the determination of content of inorganic mercury, methylmercury, ethylmercury, and phenylmercury in marine products by molecular spectroscopy with microliquid extraction. Ultrasonic extraction pretreatment is performed, C18 column and rotary evaporator are used for concentrating eluent, and liquid chromatography–ultraviolet (UV) digestion molecular spectrometry is used for analysis. Detection conditions of various forms of mercury compounds are optimized, and the content and UV digestion conditions of each component in the mobile phase are compared through experiments. The standard recovery rate of experimental samples is generally in the range of 90–106%; measured results are satisfactory, and have less interference, which provides reliable technical support for speciation analysis of mercury in marine products. |
