Abstract

The invention belongs to the field of water-processing materials, and relates to a preparation method of an aluminium oxide composite material for enriching ruthenium ion in mine-tailing wastewater. The provided preparation method comprises filling holes of ammoniated corn straws with modified aluminum oxide. The concrete technology comprises cleaning corn straws, ammoniating, modifying aluminium oxide, and preparing the composite material. Compared with corn straws, the composite material substantially improves in ruthenium ion saturation enrichment amount, and also overflow pollution of corn straw organic carbon during water processing is avoided. The prepared composite material improves the ruthenium ion enrichment amount to 144.1 mg / g, is applicable to mine-tailing ruthenium-containing wastewater, and possesses extensive market prospect.

Description

technical field [0001] The invention belongs to the technical field of water treatment materials, and in particular relates to a method for preparing an alumina composite material enriched with ruthenium ions in tailings wastewater. Background technique [0002] my country is in the stage of accelerated industrialization and urbanization, with a large consumption of mineral resources and a high degree of dependence on foreign countries. However, the global mineral product prices continue to rise, increasing the production costs of mineral product demand enterprises, and at the same time increasing the pressure on resource security. Under the tense situation of global mineral resources supply, developed countries around the world have discovered that there are business opportunities for secondary utilization in the residues and tailings left after the processing and utilization of mineral resources. As my country is a big mining country, the development and utilization of a ...
