Identification Of Fungicide Thiram Using SERS

Introduction

  • Fungicides are used for high productivity in farming.
  • Retained fungicides in soil/water is harmful.
  • Existing detection methods are time consuming and sophisticated
  • In the current study, Thiram has been detected using SERS with 103 enhancement
  • Surface-enhanced Raman spectroscopy (SERS) – high sensitivity, short detection time and nondestructive detection
Pesticide Application

Experimental Condition

  • Raman Spectrometer:
  • Model: IndiRAM P785_Tracer
  • Laser excitation source
  • Exposure time: 5 sec

  • SERS: Liquid SERS

Results and discussion

  • SERS shown enhanced Raman Signal
  • Detected minimum of 0.1 µM of Thiram on varying Concentration

Conclusion

The vibration modes of Thiram were quickly identified by using SERS Technique.
