The application of M. oleifera derived NPs in water treatment. A M. oleifera derived NPs could remove the heavy metals, ions, oils, greases, pharmaceuticals using the adsorption capacity. Photodegradation activity of M. oleifera derived NPs towards dyes, nitrate, and phosphate was shown. B NO3− removal from surface and ground water using plant extracts and synthesized nanoparticles. MOL M. oleifera leaf, MOS M. oleifera seed. The original image was adapted with permission from Ref. [43]. 2023, Shadi Rahimi
