Problems solved by technology

[0003] However, the mesopores of the above-mentioned charcoal, activated carbon, and medicinal charcoal are not sufficiently developed, and the adsorption capacity of harmful substances is weak, so it needs to be taken in large quantities, and the burden on the user is heavy.
Especially if a large amount of medicinal charcoal is taken, there will be side effects such as constipation

preparation example Construction

[0076] The method for preparing the porous carbon material is not particularly limited and may be appropriately selected according to the purpose, but the method for preparing the porous carbon material described below is preferable.

[0077]

[0078] The method for producing a porous carbon material includes a forming step, a carbide manufacturing step, and an activation step, preferably includes a deashing step, and further includes other steps as necessary.

[0079] The method for producing the above-mentioned porous carbon material is a method for producing the above-mentioned porous carbon material of the present invention.

[0080]

[0081] The forming step is not particularly limited as long as it is a step of press-molding a plant-derived material to obtain a shaped product, and can be appropriately selected according to the purpose.

[0082] The above-mentioned plant-derived material is not particularly limited, and can be appropriately selected according to the p...

Embodiment

[0168] Examples of the present invention will be described below, but the present invention is not limited to these Examples.

[0169] In the following examples, the mesopore volume, micropore volume, median particle diameter, BET specific surface area, ash content, exudation pH, and bulk specific gravity of porous carbon materials were measured as follows.

[0170]

[0171] 30 mg of a porous carbon material was prepared, and the mesopore volume, micropore volume, and BET specific surface area were measured using 3FLEX (manufactured by Micromeritex Japan GK) set to measure the relative pressure (P / P0) in the range of 0.0000001 to 0.995.

[0172]

[0173] The median diameter was measured using a laser diffraction / scattering particle size distribution analyzer LA-950 (manufactured by HORIBA).

[0174]

[0175] The bulk specific gravity is the mass per unit volume, and is obtained by dividing the mass of the porous carbon material in a predetermined shape by naturally dropp...

preparation example 1

[0183]

[0184] As raw materials, bran from Akita Prefecture is used.

[0185] The bran was heated at 600° C. for 5 hours under a nitrogen stream to obtain carbides.

[0186] Next, after coarsely pulverizing the carbide to a size of about 2 mm, it was immersed in a 1 mol % sodium hydroxide aqueous solution, and washed after removing ash.

[0187] Next, activation was performed by heating at 950° C. for 3.5 hours in a water vapor atmosphere to obtain bran-derived porous carbon material 1 .

[0188]

[0189] As the porous carbon material 2, Inakomatsu charcoal (manufactured by Charcoal Plus Lab Co., Ltd.) was prepared.

[0190]

[0191] Kuraray Coal GW (manufactured by Kuraray Co., Ltd.) (for water purifiers) was prepared as the porous carbon material 3 .

[0192]

[0193] Functional coconut shell activated carbon (manufactured by Charco Plus Lab Co., Ltd.) was prepared as the porous carbon material 4 .

Abstract

Provided is a harmful-to-health substance removing agent containing a plant-derived porous carbon material that has a mesopore volume of 0.10 cm3 / g or more.

Description

technical field [0001] The invention relates to a health harmful substance remover and a health food. Background technique [0002] Conventionally, there are many cleaning materials that are mixed with charcoal, activated carbon, or medicinal charcoal on the market. Among these products, in addition to the high cleaning effect, there are also products that claim to have a body odor removal effect or antibacterial effect, and products that have the advantage of high safety. [0003] However, the mesopores of the above-mentioned charcoal, activated carbon, and medicinal charcoal are not sufficiently developed, and the adsorption capacity of harmful substances is weak. Therefore, it is necessary to take a large amount, and the burden on the user is heavy. Especially if a large amount of medicinal charcoal is taken, there will be side effects such as constipation. [0004] Therefore, an adsorbent using a plant-derived porous carbon material has been proposed (for example, refe...
