Abstract

The invention discloses a novel composite material of activated carbon for water quality purification and a preparation method thereof. The composite material is formed by the following raw materials in parts by weight: 20-30 parts of silver-loaded activated carbon, 2-6 parts of nanometer titania powder, 1-5 parts of ammonium bicarbonate, 1-6 parts of raney nickel, 1-5 parts of sodium sulphide, 5-10 parts of medical stone, 4-8 parts of chitin, 10-16 parts of montmorillonite, 2-6 parts of calcium aluminate, and 1-8 parts of gamma-aminopropyltriethoxysilane. The novel composite material of the activated carbon for water quality purification with stable structure formed by the preparation method has the advantages of high adsorption capacity, stability in heavy metal adsorption, and no secondary pollution; nickle and titanium can be effectively prevented from falling off from the activated carbon and the medical stone, so that the secondary pollution to water is avoided, and the water quality purification effect is improved.

Description

technical field [0001] The invention relates to the field of water treatment materials, in particular to a novel composite material of activated carbon for water purification and a preparation method thereof. Background technique [0002] With the increasing eutrophication of water bodies, the water quality in my country is worrying. There are many ways to control water pollution, but the adsorption method is undoubtedly an effective measure. [0003] The activated carbon materials currently on the market for water treatment mainly use physical adsorption to separate pollutants from water. Due to its large specific surface area and developed pore structure, activated carbon has a strong adsorption capacity for dissolved organic matter in water, such as phenolic compounds, and is suitable for deep purification of drinking water. However, using activated carbon as a water treatment agent has some problems, such as the ratio of the adsorption capacity of activated carbon to t...
