5. Conclusion
In this study,
NiFe2O4@SiO2@HKUST-1
adsorbent was prepared by in in-situ self-assembly method, which is one
of the green synthesis methods,
NiFe2O4@SiO2@HKUST-1
core-shell magnetic microspheres were characterized.
NiFe2O4@SiO2@HKUST-1
application in methylene blue pollutant adsorption and influence of time
and pH factors were investigated. As a result, at the more acidic pHs,
the lower the concentration of the dye solution, the less the dye
molecule in the solution so pore volumes and surface areas will be
filled in a longer time and their removal efficiency will be higher. As
an optimum condition, within 60 minutes approximately 98% of dye
removal was observed. For this reason, the magnetic metal-organic
framework nanocomposite 30%
NiFe2O4@SiO2@HKUST-1 was
used as an optimum percentage which means that the adsorption process
was mostly multilayered on heterogeneous surfaces of the metal-organic
framework nanocomposites.
