Method for producing tripolite loading nano-TIO2 material capable of being used for water and air purification

Abstract

The invention relates to a process for preparing diatom earth loading nanometer Ti2O material for purifying water and air, which belongs to the field of material process and environmental treatment. Diatom earth raw ore is filled with water and is churned and scattered, is screened, is sunken by gravity, and is eccentrically sunken, sulfuric acid is adopted to dissolve clay-type foreign matters which are left in pore passages after ores which mutually grow with diatom earth like quartz, feldspar, mica, and clay and the like and organic matters which are mixed such as grass roots and barks and the like are removed, and diatom fine soil is attained. Further, diatom fine soil is filtered, dried, and baked, and diatom fine soil after baked is filled with water, and is churned, and is filled with acid to regulate the PH value, and is filled TiCl4 solution, and is filled with ammonia sulfate solution to proceed hydrolytic decomposition deposition reaction, and product yield after the reaction is filtered, washed, dried, and baked to attain the nanometer Ti2O material.

Description

1. Technical field [0001] The invention relates to a diatomite-loaded nano-TiO that can be used for water and air purification 2 The invention relates to a material preparation method, which belongs to the field of mineral material processing and environmental treatment. 2. Background technology [0002] Water pollution and air pollution pose a major threat to human living environment and health. Water pollution and air pollution control are directly related to human reproduction and sustainable economic development. At present, there are many methods for water and air pollution control, such as adsorption method, chemical method, physical chemical method, biochemical method, photocatalytic method and so on. Many materials, such as activated carbon, zeolite, molecular sieve, diatomaceous earth, bentonite, etc., have been processed to selectively adsorb various organic and inorganic pollutants, and are widely used in water pollution and air pollution control. However, stud...

AI Technical Summary

Problems solved by technology

However, on the one hand, zeolite molecular sieves, activated carbon, etc. are used as carrier materials, and the production cost is high, and the pore size of these carriers is too small (less than 1nm), and the pores after loading photocatalyst components (such as nano-titanium dioxide) are mostly covered, and the light transmittance is relatively low. poor, affecting the performance of the photocatalyst effect, although the production cost of natural zeolite, bentonite, sepiolite, glass, etc. On the other hand, sol-gel, liquid-phase chemical precipitation, vapor-phase deposition, melt separation and other methods have high production costs, and the existing liquid-phase deposition and impregnation methods are difficult to obtain uniformly loaded and highly catalytic nano Titanium dioxide
