Highlights

• Agglomerate forming powder materials were magnetically modified.

• Microwave synthesized magnetic iron oxide particles were used for magnetization.

• Water miscible organic solvents were used to disperse magnetic particles.

• Magnetically modified diamagnetic materials were used as organic dyes adsorbents.

Abstract

A simple method for the magnetic modification of various types of powdered agglomerate forming diamagnetic materials was developed. Magnetic iron oxide particles were prepared from ferrous sulfate by microwave assisted synthesis. A suspension of the magnetic particles in water soluble organic solvent (methanol, ethanol, propanol, isopropyl alcohol, or acetone) was mixed with the material to be modified and then completely dried at elevated temperature. The magnetically modified materials were found to be stable in water suspension at least for 2 months.
