Aim and Background: The harmful environmental effects caused by petroleum compounds have caused petroleum compounds to be considered as one of the priorities for the removal of pollutants in the environment. Therefore, finding effective techniques for removing these compounds from water is one of the most important environmental issues. The purpose of this study is to investigate oil pollutant (C16) removal using a graphitic carbon nitride (g-C3N4) nanoparticle in the presence of a bacterial consortium isolated from contaminated areas.
Materials and Methods: To investigate C16 removal, samples were collected from three stations in the northwestern catchment area of Iran contaminated with oil compounds. The synthesized nanoparticles were characterized with FTIR, XRD, and SEM characterization tests. The effect of nanoparticle concentration (50-100-150 mg/L) on the removal rate of oil pollutant (C16) was investigated. The C16 removal rate was examined by evaporation analysis in the presence of 100 mg/L g-C3N4.
Results: Morphology of the planar and porous g-C3N4 structure and the presence of g-C3N4 were proved. According to the results, in the evaporation analysis method, the highest percentage of C16 removal was observed on the last day (day 15). On the ninth day, which is the optimal time for removal, the removal of g-C3N4 nanoparticles and bacteria was observed at 37.32%. The decrease in the volume of C16 was more in the concentrations of 100 and 150 mg/L, and the largest decrease in the volume was on the 15th day, when the volume of C16 decreased to 1.8ml.
Conclusion: According to the results of this study, due to the ability of bacteria to C16 biodegradation, these bacteria can be a suitable choice for industrial use in the biodegradation process of oil pollutants.
