The synthesized metal-organic framework nanocomposites were examined
using VSM analysis at ambient temperature to investigate the magnetic
properties. Fig 4 shows the VSM magnetic analysis diagram for the
synthesized magnetic metal-organic framework nanocomposites.

framework nanocomposites.
The magnetized curves of the synthesized samples show that the
synthesized magnetic metal-organic framework nanocomposites having a
good superparamagnetic property with different magnetic saturation. In
magnetic metal-organic framework nanocomposites, as the weight ratio of
ferrite nickel to the silica substrate increases, the magnetic
saturation increasing. The parameters obtained from this analysis are
presented in Table (3). Therefore, it can be concluded that, studied
metal-organic framework nanocomposites are easily dispersed in water and
can be collected by an external magnetic field [26, 27, 47-49].
