| 總結: | Purification process on heave metal Co and Fe in liquid by using
nanoparticle magnetit (Fe3O4) adsorbent have been investigated. The effect of
particle size, concentration, remanence magnetic properties (Mr) and
amplification to reduce of metal Fe and Co contents studied in this research. The
result showed that the Fe3O4 adsorbent with the size of 11,5 nm was able to
absorb the highest content of metal ions. Procentage of reduction of Fe and Co
are 99.855% and100%, respectively. The particles which smaller particle have
the higher contact surface. Moreover, concentration 0,005 g/ml and 0,006 g/ml
gave the maximum reduction in the maximum degree of metals Co and Fe are
99.843% and 100%, respectively. The procentage of reduction of Co and Fe at Mr
of 6,17 emu/cc are 99,936% dan 100%, respectively. The magnetic properties of
absorbent would influence the reduction of metal contents.
