Abstract
The invention discloses arsenic removal modified active carbon, which is characterized by being prepared from the following raw materials in parts by weight: 5-8 parts of aluminum hydroxide, 120-130 parts of active carbon, 6-9 parts of polyethylene glycol, 3-4 parts of urea, 5-7 parts of calcium oxide, 7-9 parts of magnesium oxide, 10-15 parts of silicon dioxide, 8-10 parts of aluminum oxide, 10-15 parts of ferrous sulfate, 1-2 parts of ascorbic acid, 6-9 parts of sulfamic acid, 4-6 parts of sodium dodecyl benzene sulfonate, 4-5 parts of modified diatomite and a right amount of water. According to the invention, oxidized metals, such as calcium oxide, are used, and can remove sulfur efficiently; meanwhile, sulfamic acid is used for activating the active carbon, thus, more micropores are formed and the specific area is larger; by addition of ferrous sulfate, arsenic in water can be removed effectively, concentration of arsenic in water is reduced, and the arsenic concentration can meet the sanitary standard for drinking water. According to the invention, the technology is simple, the purification effect is remarkable, and the application foreground is substantial.
Description
Technical field
The present invention relates to a kind of modified function Material Field, relate in particular to a kind of arsenic removal modified activated carbon and preparation method thereof.
Background technology
Remove at present pollutant 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
The object of the present invention is to provide a kind of arsenic removal modified activated carbon and preparation method thereof.
Technical scheme of the present invention is as follows:
A modified activated carbon, is characterized in that being made by the raw material of following weight portion: aluminium hydroxide 5-8, active carbon 120-130, polyethylene glycol 6-9, urea 3-4, calcium oxide 5-7, magnesia 7-9, silica 1 0-15, alundum (Al2O3) 8-10, ferrous sulfate 10-15, ascorbic acid 1-2, sulfamic acid 6-9, neopelex 4-6, modification infusorial earth 4-5, water are appropriate;
