Paper Abstract

Arsenic (As) is a trace element exist in the environment, and it is one of the common poisonous elements in water, excessive intake of arsenic can cause great damage to human body. At present, mainly used laboratory detection methods of arsenic such as electrochemical method, ion chromatography, atomic absorption spectroscopy and so on, can detective arsenic, but these techniques have some problems such as low sensitivity, intractable operation and expensive. Based on the specific molecules of arsenic, we tested a new rapid detection method of arsenic solution, we prepared surface-enhanced Raman enhanced scattering substrate (SERS substrate) to complete the detection of arsenic solution. Through linear discriminant analysis, the result show that Raman spectrum has high specificity and sensitivity. The study indicated the feasibility of using SERS substrate to conduct Raman spectrum detection on arsenic, which was of great significance for the detection of arsenic in aqueous solution.
