Modifikasi Nanopartikel Magnetite Menggunakan Karbon Aktif Untuk Adsorbsi Logam Berat Tembaga Dari Air Sungai Siak Pekanbaru Riau

---

Natural sand of west coast of Sumatera Island consists of magnetic phase
such as magnetite (Fe3O4), hematite (α-Fe2O3), maghemite (γ-Fe2O3) phases or
other phase namely ilminate (FeTiO3). When the particles size of these particles
especially magnetic particles reduces ti nano size, then these particles posses a
unique property called superparamagnetic. Due to this property, this particle has
a wide range of application, One of them is for the removal of heavy metal from
contaminated water such as Siak river Water Pekanbaru.
Magnetic iron oxide Fe3O4 particles from Padang beach, West Sumatra was
synthesised using iron sand separator and ball milling method. After milling for
60 hours, the magnetic iron oxide particles were modified with activated carbon.
Activated carbon was obtained using ball milling method. The as synthesized
magnetic iron oxide particle were characterized by scanning electron microscope
(SEM) and X ray fluorescence spectroscopy (XRF). Then the magnetic iron oxide
particles were applied as adsorbents with fixed amount of activated carbon (0.8g)
for the selective removal of toxic heavy metals from Siak River water Pekanbaru.
The effects of amount of carbon doped magnetic iron oxide particles on the
amount of heavy metals removal were investigated. The adsorption process was
studied using Fourier transform infrared (FT-IR) spectroscopy and found to be
dependent on the amount of carbon doped magnetic iron oxide particles. The
adsorption of heavy metals increases when magnetic iron oxide increase.
Key words : magnetic nanoparticles, activated carbon, heavy metal, adsorption,
ball milling and Siak River water.
