Determination of Amaranth by Fluorescence Spectrometry

Abstract:

It is showed that in the buffer solution of Tris-HCl (pH=8.50), the presence of SDBS could enhance the fluorescence of AAT, and the enhanced level is linear with the concentration of amaranth in a certain range. The detection limit of amaranth is 3.27×10^-⁷mol·mL^-1.The linear range of amaranth is 1.00×10^-7- 1.00×10^-³mol·L^-1 with R =0.9920. At the same time, its mechanism is discussed by resonance light scattering and absorption spectra. Compared with other analysis methods for amaranth which have been reported, this method has a relatively wider linear range and higher sensitivity.
