Abstract

The present invention provides a C/gamma-Fe2O3 composite material recycling method, which comprises: (1) sprinkling a C/gamma-Fe2O3 composite material onto the surface of oil water or dye sewage, and carrying out bubbling stirring to completely adsorb the dye or oil; (2) electrifying an electric magnet, and carrying out magnetic recovery on the C/gamma-Fe2O3; (3) carrying out power-down on the electric magnet, dispersing the recovered C/gamma-Fe2O3 composite material of the absorbed oil or dye in an organic solvent, and carrying out bubbling stirring; and (4) electrifying the electric magnet again, carrying out magnetic adsorption on the desorbed C/gamma-Fe2O3 composite material, sprinkling in an organic solvent again, carrying out desorption, repeatedly performing the steps 3-5 times, recovering the C/gamma-Fe2O3 composite material, and drying so as to be recycled. According to the present invention, the method has characteristics of simple process and easy operation; the characteristics of the material are used to achieve the magnetic oil water separation; and the continuity is strong, the problem that the traditional material is not easily regenerated is well solved, and the resource recycling and re-use is achieved.

Description

technical field [0001] The invention belongs to the field of wastewater purification, and relates to a magnetic amorphous carbon C composite material recycling method, in particular to a C / γ-Fe 2 o 3 Methods for recycling composite materials. Background technique [0002] Carbon materials are hydrophobic adsorbents that can function in the presence of water or water vapor. Carbon materials are not only suitable for absorbing land spills, but also for absorbing water spills; and when used for degreasing on water, they will not sink after adsorption. Although carbon has many advantages, it has limitations in terms of adsorption capacity, ease of separation, and recyclability. [0003] At present, in the cold rolling process, due to the characteristics of fast pickling speed, good quality, and easy acid regeneration, hydrochloric acid pickling has become the mainstream technology in strip pickling. Generally, the pickling lines of large steel plants are equipped with picklin...
