摘要：

Silver ions cannot exist in excess in the human body. Conventional instrumental analysis methods such as atomic emission and atomic absorption are commonly used to detect Ag+, but the sensitivity is not satisfactory. Therefore, we developed a novel surface-enhanced Raman scattering (SERS) substrate with a single-layer porous silicon structure, and we completed the detection of Ag+ in domestic water and food based on this substrate. The SERS substrate with porous silicon structure has high detection sensitivity. It is found that Ag+ can be oxidized and deposited on porous silicon to change the Raman spectral properties.The results show that the Raman spectral intensity is linearly related to different content of silver ions, and the maximum linear correlation coefficient is 0.95123. The exploratory research results prove that the newly prepared SERS substrate with single-layer porous silicon is has great significance for the detection of water source and food safety.
