Method for removing fluorine ion from water by using zirconium oxide carried molecular screen

Abstract

The invention discloses application of molecular sieve loading zirconium oxide for removing fluoride ions from water. The invention also discloses a method by employing the molecular sieve loading zirconium oxide to remove the fluoride ions from water, namely absorbing and removing the fluoride ions by modified molecular sieve loading zirconium oxide from polluted water at a temperature of 10-40DEG C under the acidic or alkaline condition. The invention shows remarkable adsorption capacity superior to than of conventional adsorption materials by the time when removing fluorine contaminants from the water by the adsorption method. In addition, the invention has the advantages of simple operation, easy obtaining of materials, low cost and obvious treatment effect, thereby the invention has perfect economic and social benefits for removing the fluoride ions from source water of slightly polluted water.

Description

technical field

[0001] The invention belongs to the technical field of water body molecular sieves and oxides, and in particular relates to the application of molecular sieve-supported zirconium oxides in removing fluorine ions in water. Background technique

[0002] With the development of modern industry, the production of fluorine and its compounds is increasing. The waste water produced by the mining and processing of fluorine-containing ore, metal smelting, aluminum electrolysis, coke, glass, electronics, electroplating, fertilizer, pesticide, chemical industry and other industries often contains high concentrations of fluoride, which causes environmental pollution after being discharged into water bodies, causing people of high attention. Fluorine is one of the essential trace elements for the human body, but when the daily intake of fluorine exceeds the normal needs for a long time, it will lead to endemic fluorosis. High fluoride content in drinking water is the mo...
