Selenium is widely present in marine organisms, water quality, food and feed, and there are many methods to detect its content. Fluorescence spectrophotometry is an effective method for qualitative and quantitative determination of fluorescent substances. It is a relatively common method for the determination of selenium content. This article takes the determination of selenium content in marine organisms as an example, based on GB 17378.6-2007 "Ocean Monitoring Specifications: Part 6 Organism Analysis" 12.1 Selenium Fluorescence Spectrophotometry (Arbitration Method), using Gangdong F-380 fluorescence spectrometry The photometer measures the selenium content. The results prove that this method is simple and easy to operate, and good linearity is the ideal method for determining the content of selenium.
