Abstract
The invention relates to an iron oxyhydroxide modified active carbon desulfurizer which is prepared from the following raw materials in parts by weight: 120-130 parts of active carbon, 12-14 parts of iron oxyhydroxide, 4-5 parts of lignin sulfate, 4-5 parts of polyvinyl alcohol, 8-10 parts of modified attapulgite and an appropriate amount of water. According to the iron oxyhydroxide modified active carbon desulfurizer disclosed by the invention, the iron oxyhydroxide is used to efficiently desulfurate and dechlorinate, and the desulfuration effect is long in lasting time. The lignin sulfate is further used, so that raw materials such as active carbon can be uniformly dispersed in water. Therefore, the desulfurizer has a better water treatment effect, free from toxic substances and low in production cost, and can be repeatedly and recycled, thereby not only saving the industrial cost, but also laying a foundation for industrial application.
Description
Technical field
The method of modifying that the present invention relates to a kind of nonmetallic ore, relates in particular to a kind of hydroxyl oxidize iron modified activated carbon desulphurization agent 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.
Summary of the invention
