ABSTRACT
Objective To develop a rapid SERS detection method based on monolithic column for detection of dye adul-terated natural indigo .Methods The dyes in natural indigo were extracted and mixed with silver colloid .The spectra were re-corded after applying the mixture solution to the monolithic column since the intertwined pores in monolithic column could con-tribute 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 col-umn could be used for rapid detection of stained natural indigo .
