Aplikasi Katalitik Dari Nanopartikel Hematit Didoping Menggunakan Mangan Untu…

ABSTRACT Hematite (α-Fe2O3) magnetic nanoparticles doped with manganese (Mn) were used as a catalyst to degrade methylene blue. Hematite magnetic nanoparticles (α-Fe2O3) originate from natural sand in Logas Village, Kuantan Singingi Regency. Natural sand that has been separated using Iron Sand Separator (ISS) is separated again using Neodinyum Iron Boron (NdFeB) magnets and synthesized …
