Embodiment 1
[0070] I use rice husks as raw materials. Carbonized rice husks (manufactured by Echo Shokai) were acid-treated or alkali-treated, and then activated with steam at 960° C. for 1 hour to obtain activated carbon 1 .
[0071] The production conditions of activated carbon 1 are shown in Table 1 below. In addition, various characteristics of the activated carbon 1 were measured by the above-mentioned measurement method using a device of 3FLEX (manufactured by Micromeritics Japan Co., Ltd.). The results are shown in Table 2-1 below.
[0072]
[0073] As for the sample water, the concentration of chloroform was adjusted to 0.06±0.006mg / L. Furthermore, activated carbon 1 was filled in a 1 mL (length 80 mm) test tube having an inner diameter of 4 mm. The sample water was passed through the activated carbon-packed column under the conditions of a temperature of 20°C and a flow rate of 1,000 times. The concentration of chloroform was quantitatively determined by gas chromatography ...
Embodiment 2
[0077] I use bamboo from China which is raw materials. Activated carbon 2 was obtained by performing an activation treatment with steam at 900° C. for 1 hour on the carbonized bamboo chips (manufactured by General Co., Ltd.).
[0078] The production conditions of activated carbon 2 are shown in Table 1 below. Various characteristics of activated carbon 2 were measured by the same method as in Example 1. Furthermore, the removal rate of chloroform was also calculated|required. The results are shown in Table 2-1 below.
Embodiment 3
[0080] I use moso bamboo from Kyushu as raw materials. Bamboo fine powder (particle size (nominal): 5 μm to 500 μm, manufactured by Bamboo Techno Co., Ltd.) was carbonized at 600°C for 6 hours, and then activated with steam at 900°C for 3 hours. Thus, activated carbon 3 was obtained.
[0081] The production conditions of activated carbon 3 are shown in Table 1 below. Various characteristics of activated carbon 3 were measured by the same method as in Example 1. Furthermore, the removal rate of chloroform was also calculated|required. The results are shown in Table 2-1 below.
