AB  - Gathering and sensing of nitrate ions in the environment due to the abundant use 
      in industry and agriculture have become an important problem, which needs to be 
      overcome. On the other hand, new materials such as carbon-based materials with 
      unique properties have become an ideal choice in sensing technology. In this 
      research, the high-density polyethylene (HDPE) polymer as a carbon source in the 
      melted form was used and carbon nanoparticles in the form of a strand between two 
      electrodes were analyzed. It was fabricated between copper electrodes by the 
      pulsed arc discharge method. Subsequently, the constructed 
      metal-nanoparticle-metal (MNM) contact was employed to recognize the nitrate 
      ions. Therefore, NaNO(3), Pb(NO(3))(2), Zn(NO(3))(2), and NH(4)NO(3) samples as a 
      usual pollutant of industrial and agricultural wastewater were examined. All 
      nitrate compounds in ten different densities were tested and sensor I-V 
      characteristic was investigated, which showed that all the aforesaid compounds 
      were recognizable by the graphene nano-strand. Additionally, the proposed 
      structure in the presence of ions was simulated and acceptable agreement between 
      them was reported. Additionally, the proposed structure analytically was 
      investigated, and a comparison study between the proposed model and measured 
      results was carried out and realistic agreement reported.
