Abstract: In the analysis of melamine in various agricultural environmental samples (soil, vegetable, fish, water, sediment, etc), a suitable samplepretreatmentprocedureisnecessaryduetoitslowcontentandthecomplexmatrixcomposition,whilechromatographyandchromatography - mass spectrometry are currently widely used techniques for melamine detection . This paper summarized the recent development of detection techniques for melamine in agricultural environmental samples, focused on sample pretreatment approaches including acid and alkali extraction,organicsolventextractionandsolidphaseextraction,andanalyticalmethodsincludingHPLC,GC-MSandHPLC-MS
