Embodiment Construction

[0026] According to the principle that expanded perlite is light and porous, can float in water and has super strong surface adsorption, and has a strong adsorption capacity for persistent organic pollutants, it was combined with TiO 2 Combined with the photocatalytic ability of B-N / TiO 2 Co-doping further increases its photocatalytic ability, and prepares new environmental remediation materials that are easy to salvage and reusable for the removal of organic pollutants in the environment. The organic pollutants in organic wastewater are methyl orange, rhodamine B, phenol, polycyclic aromatic hydrocarbons, bisphenol A, etc.; the organic pollutants in organic polluted soil are phenol, polycyclic aromatic hydrocarbons, and petroleum.

[0027] 3. Preparation process:

[0028] Take 10 mL of absolute ethanol and 5-7 mL of titanium isopropoxide and pour into a beaker and stir to obtain solution A.

[0029] Mix 0.14-1.09 g of boric acid with water to form a boric acid aqueous solut...

Abstract

The invention relates to a preparation method and application of B, N and Ti co-doped floating environment repair material and belongs to the field of environment repairing.Expanded perlite low in cost and easy to separate and recycle is used as a carrier made into B and TiO2 bearing expanded perlite, and the perlite is then dried and calcined at 400 DEG C in ammonia atmosphere to obtain the B, N and Ti co-doped floating environment repair material.Organic pollutants in an environment can be efficiently degraded, and the novel low-price efficient easily-recyclable reusable organic wastewater environmental repair material is obtained by studying conditions of use and recycling method of the organic pollutants.

Description

technical field [0001] The invention belongs to the field of environmental restoration, and in particular relates to a method for preparing and using an environmental restoration material for removing organic pollutants in water bodies and soil environments. Background technique [0002] The problem of organic pollution of water and soil caused by chemical industry and chemical agriculture is becoming more and more serious. There are also serious organic pollution in the relocation sites of some chemical factories and pesticide factories, as well as in the water and soil around oil mines. Therefore, how to remove pollutants from pollution Removal from the environment has become an urgent scientific problem to be solved. At present, the removal of organic matter in water by adsorption is considered to be the most effective means. Granular activated carbon, adsorption resin, clay minerals, etc. have all been applied to the removal of organic pollutants in water bodies. [00...
