Overview

Experimental study demonstrates effective degradation of aqueous acephate pesticide using silicon carbide and zerovalent iron under UV and solar light, highlighting a low-cost wastewater...

Key Points

  • To assess the photocatalytic degradation efficiency of commercial acephate pesticide in aqueous solutions using silicon carbide and zerovalent iron under solar and UV radiation.
  • Tested advanced oxidation processes across varying pH levels, catalyst amounts, and irradiation durations up to 360 minutes in single and mixed catalyst setups.
  • Compared degradation efficacy under solar versus ultraviolet radiation in the presence of oxidants with zerovalent iron (ZVI) or silicon carbide (SiC).
  • Characterized chemical degradation products formed during the photocatalytic reactions using Fourier-transform infrared (FTIR) spectroscopy.
  • Zerovalent iron with oxidant yielded 93.3% removal under UV light and 88.6% removal under sunlight after 360 minutes under optimal conditions.
  • Silicon carbide with oxidant achieved 85.1% removal under UV irradiation and 82.2% removal under sunlight after 360 minutes.
