Abstract
Objective To develop a rapid SERS detection method based on monolithic column for detection of dye adulterated natural indigo. Methods The dyes in natural indigo were extracted and mixed with silver colloid. The spectra were recorded after applying the mixture solution to the monolithic column since the intertwined pores in monolithic column could contribute for the distribution of silver nanoparticles. Results SERS signals of malachite green dyed natural indigo at quantity as low as 500 μg/kg could be obtained. Conclusion This simple,fast and specific SERS detection method based on monolithic column could be used for rapid detection of stained natural indigo.
