【 摘 要 】

By coupling solid-phase microextraction (SPME) with surface-enhanced Raman scattering (SERS), a facile method was developed for the determination of ferbam, a pesticide often used in fruits and vegetables. It is a potential carcinogen. The SPME substrate was made by free settling of rod-like ZnO nanomaterials on a aluminum sheet. The extraction procedure for ferbam was performed in a simple solution, and then the ferbam was determined using SERS after uniformly dropping a SERS-active substrate (gold nanoparticles, AuNPs) onto the surface of the SPME substrate. In this method, qualitative measurement in extraction precedure takes only 5 minutes. The lowest detectable concentration of ferbam is 0.01 ppm. The newly developed method is fast, convenient and sensitive in the determination of ferbam in solution.
