Nickel oxide nanoparticles were prepared using solid-state thermal decomposition of NiCl2 at the presence of maleic acid at 600°C, characterized by FT-IR spectroscopy, XRD, FE-SEM, and applied as a new adsorbent for the removal of methyl green (MG) from aqueous solution. FT-IR and XRD results confirmed the preparation of cubic NiO nanoparticles. SEM image showed that NiO nanoparticles have a wide size distribution from 50 to 200 nm. The pH of the solution, adsorbent dosage, and contact time effect on MG removal efficiency were considered. The uptake of MG was determined to be >96% in 60 min and adsorbent dosage of 0.02 g
