Carbendazim is a broad-spectrum fungicide that, despite its low toxicity to humans and animals, can pose hazards such as liver disease and chromosomal aberrations due to residues on crops. Therefore, reliable detection methods are crucial. Surface-enhanced Raman spectroscopy (SERS), as a highly sensitive and specific detection method, has broad application prospects in the detection of carbendazim. This study investigated effects of various inorganic salts as aggregating agents on the detection of carbendazim utilizing SERS. The objective was to optimize detection conditions and improve the sensitivity and accuracy of carbendazim detection. Four inorganic salts (MgSO₄, NaCl, Na₂CO₃, and KI) were selected, for their ability to significantly enhance SERS signals by influencing the aggregation of silver nanoparticles (AgNPs). The results revealed that SERS signals can be significantly affected by different types, concentrations, and mixing times of inorganic salts. Specifically, 0.2 mol/L MgSO4 was identified as the optimal aggregating agent, with the best protocol involving mixing the analyte with the silver sol before adding the aggregating agent and mixing for 20 minutes. Under these conditions, the sensitivity and accuracy of SERS detection of carbendazim were significantly improved, where a detection limit of 0.1 μg/mL was achieved. This study proposes a simple and efficient method for carbendazim detection, significantly enhancing the reliability of the SERS signal, it provides effective technical support for high-sensitivity detection of carbendazim and demonstrates promising prospects for broad application.
