Scope

Scope: This document specifies a method for rapidly determining the residual amount of malachite green in fish meat using surface-enhanced Raman spectroscopy. This document is applicable to the rapid screening and detection of malachite green in fish meat using surface-enhanced Raman spectroscopy. Main technical content: The residual malachite green in the sample is extracted with acetonitrile, purified by a neutral alumina column, and then measured using a surface-enhanced Raman spectrometer. After the malachite green molecules are mixed with a surface-enhancing agent, the target molecules adsorb onto the surface-enhancing nanoparticles, thereby enhancing their Raman scattering signal. The surface-enhanced Raman spectrometer can qualitatively detect malachite green by automatically identifying characteristic peaks.
