Research demonstrates removal efficiency of 83% from water using nickel nanoparticles, highlighting their potential in water treatment.
This research examines the potential of nickel nanoparticles (Ni NPs) as promising adsorbents for removing microplastics from water. Ni NPs were prepared using chemical reduction and then characterized using SEM, XRD, UV-vis, FTIR and magnetometry. The maximum removal efficiency of the microplastic was accomplished in 90 min and a pH of 5 (83% removal efficiency). The adsorption of microplastic by Ni NPs followed the Langmuir and Freundlich isotherms. The Ni NPs were cost effective and environmentally benign when compared to many other nanosized materials. The results demonstrate that Ni NPs are potentially useful for advanced water treatment systems that remove microplastic pollutants.
