(57) [Summary] [Problem] A pollutant that can be widely used in air, water, and soil, has a high adsorption effect for removing chemical substances, odors, heavy metals, oils, etc., and has a long-lasting effect. An adsorbent and an adsorption method. SOLUTION: By making bamboo charcoal having an adsorption action into a fine powder of 5 μm or less, as a result, the effective surface area is about 250 times as large as a bamboo charcoal powder of the same weight, for example, about 325 mesh and relatively large particles. And a sufficient adsorption effect can be obtained even with a small amount. Another advantage of making the particles finer is that, in addition to methods such as coal laying, burying coal, and coal bed, it is possible to mix or impregnate raw materials such as building materials, fibers, and paper products. . Bamboo charcoal purifies water and soil, in addition to the adsorptive power, Microbial curtains are formed on the inner surface of bamboo charcoal to produce the action of decomposing organic substances such as water by microorganisms, and the action is not immediate, but can be maintained for a long period of time. |
