Trace Benzidine Detection by Surface Enhanced Raman Spectroscopy
摘要
Abstract
Surface-enhanced Raman scattering ( SERS) -active silver colloid was prepared by a chemical method and characterized by transmission electron microscopy, scanning electron microscopy and UV-Vis spectroscopy. Silver colloid was chosen as SERS substrate to detect trace benzidine in aqueous-solution and the SERS peaks were assigned. The influence of aggregating agent (MgCl2) to the SERS was also investigated. The results indicate that SERS intensity firstly increases and then decreases when the concentration of MgCl2 is increased. There is an optimized concentration of MgCl2. The limit of detection for benzidine is around 10 mol/L under the optimized condition.关键词
