Reparasi Nanopartikel Magnetik Dengan Metode Ball Milling Dua Tahap Dan Aplikasinya Untuk Adsorpsi Logam Berat Dalam Air Sungai Siak

Environmental pollution by heavy metals becomes a serious problem with the
increasing use of heavy metals in the industrial field. One of the widely used
methods for removing heavy metals from liquid waste is adsorption using
magnetic nanoparticles. Samples of beach sand that have been processed with an
Iron Sand Separator (ISS) and separated by NdFeB (Neodymium Iron Boron),
crushed by ball milling for 60 hours using a ball size variation of 0,5; 0,7; and 1,5
cm. The product is called ball milling product phase I (PBMT I).PBMT I is
separated again by using NdFeB magnets, then in ball milling phase II with a time
variation of 20, 40, and 60 hours (PBMT II). The suseptibility value of the sample
was obtained from the magnetic induction value measured using the Magnetic
Pasco Ps-2162 Probe. The crystal size and magnetic phase of magnetic
nanoparticles are determined by the X-Ray Diffraction (XRD) method and heavy
metal adsorption is determined using AAS (Atomic Absorption Spectroscopy).
The results showed that total magnetic induction, magnetic suseptibility, and mass
suseptibility increased with increased ball milling time. XRD results show that
magnetic nanoparticles have 2 magnetic phases namely magnetite with
cubic crystal structure and hematite with monoclinic crystal
structure. AAS results showed that Cu ion adsorption increased with increasing
milling time, whereas the percentage value of adsorption in a row is 27,2%,
40,5%, and 64,7%, while for Pb adsorption ions decreased with increasing milling
time of 46,1%, 35,6%, and 11,8%, respectively.
Keywords: beach sand, ball milling, magnetic nanoparticles, X-ray diffraction
(XRD), heavy metals, and adsorption
