Estimating the term…
The present invention provides a water treatment composition capable of effectively adsorbing pollutants in water treatment. The composition can be rapidly separated by use of magnetic force, and hence is excellent in workability. The composition comprises magnetic particles for water purification, and is suitably used in water treatment for removing oils and the like in water. The magnetic particles are prepared by subjecting magnetic powder to surface treatment with a particular organometallic compound. The organometallic compound comprises a metal atom connected to an alkoxy group and an amphipathic organic group.
Magnetic particles for water purification, comprising magnetic powder having a surface with which amphipathic groups are combined via metal atoms.
Magnetic particles for water purification, prepared by subjecting magnetic powder to surface treatment with an organometallic compound comprising a metal atom connected to an alkoxy group and an amphipathic organic group.
A preparation process of magnetic particles for water purification, wherein an organometallic compound comprising a metal atom connected to an alkoxy group and an amphipathic organic group is mixed with magnetic powder and then stirred so that the magnetic powder is subjected to surface treatment.
