Abstract
An iron ore slag modified active carbon desulfurizer is characterized by being composed of following raw materials in parts by weight: 100 to 120 parts of active carbon, 20 to 24 parts of milk protein, 4 to 5 parts of acrylonitrile, 3 to 4 parts of soybean oil, 12 to 14 parts of montmorillonite powder, 10 to 12 parts of iron ore slag, 8 to 10 parts of modified attapulgite, and a proper amount of water. The preparation method uses iron ore slag, which has been subjected to a high-temperature treatment and contains iron oxides, to remove sulfur, achieves waste utilization, and saves the energy and cost; modified attapulgite and jade powder are added to absorb harmful materials such as formaldehyde and give off materials beneficial for human bodies. The preparation method has the advantages of simple production process and low cost, is capable of increasing the energy utilization rate, and is suitable for industrial production.
Description
Technical field
The present invention relates to a kind of method of modifying of nonmetallic ore, relate in particular to a kind of iron ore tailings modified activated carbon sorbent 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.
