Abstract

The invention provides a renewable green environment-friendly material and a preparation method and application thereof. The renewable green environment-friendly material is prepared by calcining an animal bone at a temperature of 500 to 650 DEG C to remove organic components so as to form a porous structure and then taking out a sintered product for air cooling. The environment-friendly material comprises a porous compact bone with porosity of 42 to 51.5% and a porous spongy bone with porosity of 75 to 85% obtained after calcination of the animal bone, and the main component of the material is hydroxylapatite with a crystal grain size of 100 to 300 nm. The environment-friendly material is applicable to treatment of heavy metal ions in wastewater. In use, the environment-friendly material is put into wastewater for treatment of the wastewater. The environment-friendly material has the advantages of strong renewability, greenness, energy conservation and environment friendliness; the preparation method is simple, needs low cost, is suitable for industrial production, can fully utilize the resource of waste animal bones and reduces environmental pollution; the material has a high heavy metal ion adsorption rate, as high as more than 90.1%, so the material has wide application prospects.

Description

technical field [0001] The invention belongs to the field of environment-friendly materials, and in particular relates to a renewable green environment-friendly material and its preparation method and application. Background technique [0002] With the development of industry, wastewater containing toxic heavy metals is extremely harmful to the ecological environment. Heavy metal wastewater mainly comes from mine tunnel drainage, waste rock field leaching water, ore dressing plant tailings drainage, non-ferrous metal smelting plant dust removal drainage, non-ferrous metal processing plant pickling wastewater, electroplating plant plated parts washing water, iron and steel plant pickling drainage and electrolysis And other industries. After they enter the environment, they cannot be biodegraded, and most of them participate in the food chain cycle and accumulate in the organism, destroying the normal physiological and metabolic activities of the organism and endangering huma...
