Embodiment 1

[0020] The activated carbon fibers were soaked in copper sulfate solution for 5 hours, dried naturally, and then dried at 200°C to obtain the adsorption material.

[0021] After analysis, the activated carbon content is 335g / m 2 , copper sulfate content is 67g / m 2 .

Embodiment 2

[0023] The activated carbon fiber base net is sprayed with a solution with a copper sulfate concentration of 8wt% and a binder carboxymethyl cellulose concentration of 2wt%, baked and dried at 90°C, then sprayed with the solution, baked and dried at 90°C, and carried out 4 Once sprayed and dried, the adsorbent material is obtained.

[0024] After analysis, the activated carbon content is 480g / m 2 , copper sulfate content is 82g / m 2 .

Embodiment 3

[0026] Soak activated carbon fiber in copper sulfate solution for 3 hours, let it dry naturally, then spray it with a solution with copper sulfate concentration of 12wt% and binder carboxymethyl cellulose concentration of 3wt%, bake and dry at 95°C, and then use the The solution was sprayed, baked and dried at 95°C, and the spraying and drying were carried out 3 times in total to obtain the adsorption material.

Abstract

The CS2 adsorbing material is active carbon fiber with attached copper sulfate. It is prepared through soaking active carbon fiber in copper sulfate solution and drying; or through spraying copper sulfate solution to active carbon fiber and stoving; or through soaking active carbon fiber in copper sulfate solution, drying, spraying copper sulfate solution to active carbon fiber and stoving. The CS2 adsorbing material has excellent CS2 adsorbing capacity, and may be used for adsorbing CS2 in both opened space and sealed space so as to purify air.

Description

technical field [0001] The invention relates to adsorption and purification materials, in particular to a material for adsorption of carbon disulfide. Background technique [0002] Carbon disulfide is a flammable liquid with chemical formula CS 2 , Molecular weight 76.14, the pure product is colorless, with aromatic smell and sweet taste. The industrial product is a yellow liquid with an unpleasant smell of rotten radish. Melting point -112°C, boiling point 46.3°C, density 1.263g / cm 3 (20°C), not volatile, generally accumulate near the ground. [0003] Carbon disulfide is commonly used as a dissolving agent in industry to make viscose fiber, cellophane and carbon tetrachloride. Due to unreasonable process design and ineffective safety protection measures in the above-mentioned production and use process, it may cause certain pollution to air, water and food. Human contact can cause adverse reactions or chronic poisoning. [0004] Carbon disulfide mainly comes from the ...
