The present invention provides a functional powder capable of effectively adsorbing impurities in water treatment. The powder can be rapidly separated by use of magnetic force, and hence is excellent in workability. This functional powder comprises magnetic particles having surfaces modified with hydrophobic groups and hydrophilic groups loaded thereon. The hydrophobic groups have a function of adsorbing the impurities, and the hydrophilic groups have a function of dispersing the powder stably in water. The numbers M and N of the hydrophobic groups and the hydrophilic groups, respectively, satisfy the condition of 0.2

An oil-adsorbing particle composite and a water-treatment method using the same are provided. The particle composite is capable of selectively adsorbing contaminants such as oils contained in industrial and household wastewaters. The water-treatment method is capable of eliminating contaminants from the wastewater using the composite. The particle composite includes water-insoluble organic polymer particles, magnetic particles and a resin binder, the resin binder bonding the polymer particles and the magnetic particles. The polymer particles have an oil-adsorbing characteristic. The magnetic particles have a magnetic characteristic for a rapid collection of the composite using magnetic forces. The method includes dispersing the particle composite in contaminant-containing water, making the particle composite adsorb contaminants to separate the particle composite from the water after the adsorbing.
