Determination of residue of the herbicide fluridone in fish

摘要

The aim of this research was to develop an analytical method to detect and quantify residues of fluridone in fish. The herbicide was extracted from edible parts of fish, concentrated in florisil cartridge and then analyzed by HPLC. The detection and quantification were performed by UV absorbance (313 nm). The correlation values obtained for the linearity of the detector and the method were 0,99983 and 0,99987, respectively. The recovery coefficient ranged from 60 to 73%. The detection limit was 20 mg kg-1.
