Abstract

Boric acid modified active carbon is prepared by the following raw materials by weight: 150-170 parts of wood chip, 15-20 parts of boric acid, 7-9 parts of attapulgite, 5-7 parts of monoglyceride stearate, 7-9 parts of bentonite, 5-7 parts of lime, 4-6 parts of calcium carbonate, 3-5 parts of diethanolamine, 2-4 parts of tetraethylenepentamine, 4-5 parts of modified diatomite, and a proper amount of water. The boric acid modified active carbon is activated and modified by boric acid, so as that the active carbon has uniform texture and developed micropore gaps, and adsorption capability is greatly enhanced; the attapulgite and the bentonite, after high temperature activation, enhance absorption function of the active carbon, and simultaneously have microbe growth inhibition property, acid and alkali resistance, corrosion resistance and mildew resistance; simultaneously, calcium oxide and calcium carbonate are added for high efficiency desulphurization; and wood chip is used as a raw material which has advantages of cost low and environmental protection, and is suitable for gas phase and water phase purification.

Description

A kind of boric acid modified active carbon and preparation method thereof

Technical field

The present invention relates to a kind of modified function Material Field, relate in particular to a kind of boric acid modified active carbon and preparation method thereof.

Background technology

Along with scientific and technological development, the progressively construction of modernization industry, various chemicals are exploited, and have brought facility, simultaneously because chemicals has produced environment and the harmful material of human body, the problem that has also become people to have to face to people's life.

Current airborne pollutant is mainly the toxic and harmful producing in the gas that produces of industrial fuel burning, vehicle exhaust, production.It is mainly to contain a large amount of noxious materials in the sewage of industrial production discharge that water pollutes, and also has the sewage in people's life to produce a lot of harmful substances.In people's life, also have and many times need to remove toxin, such as air conditioning filter has a lot of bacteriums, toxin on the net, newly-decorated has the harmful substances such as formaldehyde, all needs to remove toxin.All remove at present toxin and often use adsorbent, mainly contain silica gel, activated alumina, active carbon, molecular sieve etc., also have in addition for certain compositional selecting absorption and the sorbing material of development.But the most adsorption capacity of these adsorbents is limited, need to study different adsorbents for different requirements, bring into play best effect.Meanwhile, find new raw material, to strengthen adsorption effect, cost-saving.
