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
by the ball milling method for 120 hours and is called BM I Products. BM I
products are divided into three parts (BM I A, BM I B , and BM I C) the same
amount then doped with Mn as much as 0%, 10%, and 20% of the total mass and
milled by ball milling for 20 hours. The product resulting from doping of
elemental Mn is called BM II product. Poduk BM II was characterized using a
Vibrating Sample Magnetometer (VSM) to determine the magnetic properties of
the product. The result of characterization using a Vibrating Sample
Magnetometer (VSM) is Loop hysteresis which shows that BM II products have
hard magnetic properties. Testing the ability of Mn-doped hematite magnetic
nanoparticles as a catalyst in degrading methylene blue using the Uv-Vis
spectrophotometric method and showed excellent ability to degrade methylene
blue. The percentage degradation of methylene blue using hydrogen peroxide
(H2O2) plus 0%, 10% and 20% Mn doped hematite catalyst after 14 hours of
reaction was 87.305%, 99.627% and 98.880%.
