AB  - The present study focused on exploring the potential of Ag-ZnO composites for 
      complete mineralization of imidacloprid with the aim to sustain the pollutant 
      free safe water supply. The composites were prepared by hydrothermal method and 
      characterized by Scanning electron microscope (SEM), Energy dispersive X-ray 
      crystallography (EDX), X-ray diffraction (XRD) and band gap measurements. These 
      composites were used to study the UV irradiated degradation of imidacloprid while 
      optimizing the process parameters such as time of UV irradiation, pH of medium, 
      pesticide concentration and composite loading. The results of the study revealed 
      an increase in photodegradation of imidacloprid by Ag-ZnO composites than pure 
      ZnO. Temperature and catalyst loading had a positive effect on degradation 
      efficiency, while an inverse relation was observed between pesticide 
      concentration and degradation. Moreover, no harmful degradation products of 
      imidacloprid were observed in GC-MS analyses that confirmed its complete 
      mineralization.
