Abstarct: Organic pollutants, especially of the aromatic type, which are obtained from various pharmaceutical, chemical, textile, etc. industries, are often toxic, stable and highly resistant, and for this reason, their removal and decomposition is a very difficult task. In this research, graphite nano composite g-C3N4 doped It was used on CoFe2O4, which has magnetic properties and is attracted to a magnet, to destroy two colors of methyl orange, eariochrome black T, soluble in water, and 62% destruction was achieved. For this purpose, g-C3N4 was first synthesized from melamine and on CoFe2O4 for magnetization and separation. Photocatalyst was doped. The structure of this compound was characterized and confirmed using non-destructive XRD, FESEM and FT-IR techniques. Parameters such as solution pH, amount of Photocatalyst, duration and concentration of the initial solution were evaluated. According to the obtained results, increasing the amount of Photocatalyst, reducing the concentration of pollutants in pH = 9 at an ambient temperature of 〖25〗^(°C) and a duration of 120 minutes showed its optimal performance for the degradation of 2 dyes. Kinetic analysis showed that this process follows the pseudo-first order model. By increasing one drop of hydrogen peroxide, the destruction percentage increased to 93%.To check the stability of the Photocatalyst and its recyclability, the synthesized compound was reused three times under optimal conditions, which showed a good percentage of degradation, and this indicates its suitable capability.
