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.

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].
