The invention discloses a preparation method and application of melamine bismuth complex powder, and relates to the technical field of complex material preparation and sewage treatment. First, (Bi(NO 3 ) 3 ยท5H 2 O) was dissolved in deionized water to prepare an aqueous solution of bismuth nitrate; then at room temperature, melamine (C 3 N 3 (NH 2 ) 3 ) was added to the aqueous solution of bismuth nitrate, The melamine bismuth complex powder can be obtained after ultrasonic dissolution and coordination reaction. In the invention, different amounts of melamine can be used to obtain melamine-bismuth complexes such as rod-shaped, ribbon-shaped, flake-shaped and disc-shaped, thereby realizing the controllable preparation of melamine-bismuth complex powders in various forms. The prepared melamine bismuth complex powder has good light absorption performance and heavy metal deposition ability, can effectively remove various pollutants in the water system, and is expected to be used as a new material for sewage treatment. |
