Growing human and industrial activity causes organic contaminants like dyes to contaminate water resources. This study created a nanocomposite photocatalyst for the breakdown of organic dye pollutants called a chitosan nanoparticle doped activated carbon (CSNPs@AC). The creation of the chitosan nanoparticle-doped activated carbon (CSNPs@AC) nanocomposite was confirmed by XRD, UV, FT-IR, and SEM-EDX studies. Using malachite green (MG) as a model organic dye, photocatalytic degradation was examined under UV and visible light. During photocatalytic degradation, it was discovered that the absorbance decreased in direct proportion to the drop in dye concentration. With MG, the degeneration happened more quickly. Additionally, the photocatalyst was more effective at degrading malachite green (MG) under UV light.
