摘要：This paper reports accurate synthesis of a new type of surface-enhanced Raman spectroscopy (SERS) substrate based on gold nanoparticles decorated 201 red silanized diatomaceous supports. The developed SERS substrate is easy to fabricate, cost effective and offers sensitive rapid detection. The performance and stability of the SERS substrate was investigated and the results showed good SERS activity of substrate that can last for more than 6 months. Tiazophos and phosmet pesticides in aqueous solutions can be detected clearly at a low concentration of 0.01 mg/L. The new substrate was applied to detect triazophos in apple pulp at 0.2 mg/kg. The results indicate that this substrate have good potential in rapid monitoring of pesticide residues in fruits and could be suitable for field-based applications, and routine laboratory analysis of chemicals.
