Adsorption, Antimicrobial, Biosynthesis, Manganese oxide, Removal


Manganese sulfate and Punica granatum plant extract were used to create MnO2 nanoparticles, which were then characterized using techniques like Fourier transform infrared spectroscopy, ultraviolet-visible spectroscopy, atomic force microscopy, X-ray diffraction, transmission electron microscopy, scanning electron microscopy, and energy-dispersive X-ray spectroscopy. The crystal's size was calculated to be 30.94nm by employing the Debye Scherrer equation in X-ray diffraction. MnO2 NPs were shown to be effective in adsorbing M(II) = Co, Ni, and Cu ions, proving that all three metal ions may be removed from water in one go. Ni(II) has a higher adsorption rate throughout the board. Co, Ni, and Cu ion removal efficiencies were 32.79%, 75.00%, and 30.20%, respectively. Two species of bacteria and one type of fungus were examined at three different use concentrations if possible of MnO2 nanoparticles. Antibiotics like Amoxicillin and Metronidazole were used as a control group to see how the findings stacked up.
