摘要：

Amaranth is a synthetic pigment widely used in daily use. In this paper, silver nanorods (AgNR) array substrates were prepared by oblique angle deposition (OAD) to detect the amaranth in water based on surface-enhanced Raman spectroscopy (SERS) rapidly and quantitatively. The theoretical spectrum and their characteristic peaks were simulated by density functional theory (DFT). The results showed that the main characteristic peaks of amaranth were located at 1345 cm(-1) and 1361 cm(-1). The signal intensity of amaranth increased linearly with the concentration in the range of 1 mg/L similar to 100 mg/L, and the detection limit was 1 mg/L.
