摘要：

Using amino silica modified with fluorescein isothiocyanate (FITC), a quick fluorescence analysis technique is used for the detection of 3-monochloropropane-1,2-diol (3-MCPD). At 100 degrees C and pH 8.5, FITC-modified amino silica exhibits the lowest fluorescence intensity in the presence of 3-MCPD. This can predominantly be explained mostly explained by 3-MCPD's capacity to occupy the amino group that FITC normally binds to. The fluorescence intensity of FITC-modified amino silica was greatly quenched by 3-MCPD's reaction with the amino group under alkaline conditions, and the fluorescence i...
