Abstract
Water pollutants constitute a significant environmental concern today. Organophosphorus compounds, notably parathion, represent a critical category of water pollutants. Their extensive usage poses substantial risks to human health and the environment, necessitating their removal from water sources. This study focuses on the photocatalytic degradation of parathion, utilizing a g-C(3)N(5)/CuS/AgNPs nanocomposite synthesized through a combination of hydrothermal and ultrasonic methods. The nanocomposite was characterized using microscopic and spectroscopic techniques and demonstrated the capacity to degrade approximately 94.90% of parathion in the presence of visible light within one hour at pH 6. Parameters such as pH, initial pollutant concentration, and photocatalyst concentration were optimized. The study's findings highlight that (•)O(2)(-) and (•)OH play a predominant role in the degradation process of this contaminant.
